Dwarf Mexican crawfish comes from Lake Pátzcuaro, a volcanic crater lake in Michoacán which is located in the southwest of the major city of Morelia, Mexico. Wild individuals of this crayfish are mostly tan, brown, and rust color.
However, Dwarf Mexican crawfish are also available in bright colored morphs that are dramatically different from their normal, relatively drab, wild type coloration. The orange color morph of the dwarf species originated in the Netherlands (bred by Juan Carlos Merino in the 1990s).
This color morph also called “CPO – Cambarellus patzcuarensis var orange” is a very attractive and popular strain among hobby keepers. Actually, it completely took over the pet niche for this species. Once again, this mutation comes from the crayfish being bred in captivity and not in the wild.
The lifespan of these tiny bright creatures is only about 2 years but have been known to live even a little bit longer. -

🚨 ARTHROPOD OF THE DAY 🚨
Sand fly adults are small flies – only about 3 mm long – and are golden, brownish or gray colored. They have long, piercing mouthparts that are well adapted for sucking blood from their selected host. Sand flies hold their hairy-looking wings in a vertical V-shape when at rest, a characteristic that distinguishes them from some other small flies. Also, the six legs on the adults are extremely long, being longer than the insect’s body.
Female sand flies are blood feeders, but the males do not feed on blood. Females must consume a blood meal before they are able to develop eggs. However, both males and females also consume sugar-related nutrients that come from plant nectar or honeydew. Sand fly hosts vary a great deal. Some species feed on both mammals and reptiles, while Lutzomyia shannani, a common sand fly species in Florida and other coastal states feed on white-tailed deer, horses, donkeys, mules, cattle, swine, raccoons, rodents, birds and humans.
In general, sand fly bites are very painful. Most flies that bite humans feed during the evening and throughout the night. In some cases, flies will attack in the daytime, if they are disturbed while resting.
In general, sand fly females must consume a blood meal to develop eggs.
Sand flies develop by complete metamorphosis, which means they go through four developmental stages: egg, larvae (grub), pupae (cocoon) and adult. Sand flies complete their life cycle within 1-3 months, depending on the sand fly species and their environmental conditions. -

The Jewel Stag Beetle, (Lamprima adolphinae) is a species of stag beetle from Indonesia. They are known for the many different metallic colours they come in, such as gold, green, blue and purple. They are a relatively small species coming in at around 50mm for major males.
Lamprima adolphinae is endemic to New Guinea. The species is said to occur as a neozoon in Japan.
Characteristics
The species is characterized by a very pronounced sexual dimorphism. The males can reach a body length of 27 millimetres, the females are considerably smaller and grow up to 22 millimetres long. The pronotum and elytra are metallic green in color, the head and abdomen are coppery reddish. The pronotum is wider than long and reaches the width of the elytra. The male's body surface is smooth and shiny, with sparse, inconspicuous spots.
Lamprima adolphinae occurs in many different color variants, especially in bred animals. For example, there are breeding forms in blue, red, black and other colors.
The animals feed on tree sap and overripe fruit. The females lay their eggs in rotten logs. To do this, they make tunnels in the dead wood. The larvae live and feed on rotten hardwood. Depending on the temperature and available food, they need 9 to 13 months to develop. The male larvae can reach a length of up to 60 millimeters, the female larvae up to 40 millimeters. -

Dorylus ants, members of the Formicidae family, contain over 61 different species and are the most aggressive ants on the planet. Aside from their hostile nature, fierce bite, and piercing sting, they overtake their prey in large numbers.
These ants are known for their nomadic existence and their manner of hunting in massive swarms that are known to carpet the forest floor. As they creep across the land, insects and other mammals flee from the armies. The unfortunate animals that are too sick or injured to move may be consumed by the ants. But the majority of the driver ant diet consists of insects and earthworms.
Driver ants not only swarm the ground but can cross water, scale walls, and cliffs, and climb trees. They do this by creating bridges or tunnels with their bodies. The columns they create are flanked by the larger soldier ants, while the smaller workers can pass through safely.
The ants are found in Central, Eastern, and South Africa and tropical Asia. Their habitats are rainforests, grasslands, and scrublands. The ants are nomadic and live in temporary underground nests, which they relocate often. -

🚨 ARTHROPOD OF THE DAY 🚨
The Puss Moth, Cerura vinulais, is well recorded through most of the southern half of the British Isles becoming less common in the north.
This distinctive nocturnal moth flies in a single generation between May and July when it is attracted to light.
It can be found in a wide range of habitats including moorland, gardens and open woodland.
The caterpillars are dark brown at first with a pair of small horn like protuberances on the dorsum behind the head.
A pair of red tipped, modified rear claspers, over half the body length long, are raised to warn off predators when disturbed.
Within 7 days the caterpillars have changed into a third instar – the subtle shades of brown, yellow and green designed to blend in with the foodplant leaves.
The caterpillars continue to feed on top of leaves as they grow. In strong sun light their dark silhouette on the upperside of a leaf may at times be seen when looking up from below. -

The House Centipede (Scutigera coleoptrata) is a yellowish grey centipede with 15 pairs of legs. Originally native to the Mediterranean region, the species has spread to other parts of the world, where it usually lives in human homes. The House Centipede is an insectivore that kills and eats insects.
In an act of defence, when one of the house centipedes legs is held down, it drops that leg in hopes that the attacker will be distracted by the temporarily twitching appendage. Unlike most other centipedes, House Centipedes and their close relatives have well-developed, faceted eyes.
Outdoors, house centipedes prefer to live in cool, damp places. Most live outside, primarily under large rocks, piles of wood and especially in compost piles.
Within the home, these centipedes are found in almost any part of the house, most commonly, they are encountered in basements, bathrooms and lavatories, where there is a lot more water, but they can also be found in dry places like offices, bedrooms and dining rooms.
Because they eat household pests, house centipedes are considered among the most beneficial creatures that inhabit human dwellings, but because of their alarming, frightening appearance and painful bite, few homeowners are willing to share a home with them. They do not cause damage to food or furniture.
The house centipede is capable of biting a human, but this seldom occurs. When it does, it is no worse than a minor bee sting. The worst one can usually expect from a house centipedes bite is some pain and a slight swelling at the location of the bite. -

Nearly the same size as the emperor scorpion, the Javanese jungle scorpion is much harder to find, and as a result it’s highly-sought after. It’s native to the rainforests of Indonesia, and as such it likes a humid, wet environment. They’re somewhat aggressive, but they prefer to pinch rather than sting.
These venomous arachnids are native to the tropical rainforests of Java, Indonesia, where they can be found hiding under logs and rocks, or burrowed in the ground. Javanese Jungle Scorpions, also known as Heterometrus javanensis, are part of the family Scorpionsidae. They belong to the same genus as the popular pet species, the Emperor Scorpion (Pandinus imperator). However, Javanese Jungle Scorpions are generally larger and more robust in size, with a distinctive orange coloration on their pincers and tail. They can reach lengths of up to 8 inches, with a lifespan of 5-7 years in captivity.
Javanese Jungle Scorpions are easily recognizable by their large size and orange coloration on their pincers and tail. They have eight legs and two pincers, or pedipalps, which they use for grasping and tearing apart their prey. They also have a venomous stinger on their tail, which they use for self-defense and capturing prey.
Like all scorpions, Javanese Jungle Scorpions undergo a process called metamorphosis, where they go through several stages of development from birth to adulthood. When they are first born, they are called “scorpionids” and are tiny, translucent versions of adult scorpions. They will molt, or shed their exoskeleton, several times as they grow and develop. -

Clymene moth (The Blessing Moth) is an Erebidae moth indigenous to the eastern parts of North America. English naturalist Peter Brown first described this species in 1776.
When opened, the wings appear creamy-yellow, partially bordered in a dark brown line extending inward from the margin lying close to the anal angle. When closed, the color and pattern remain unchanged, with the brownish-black markings forming a cross.
The larvae are brownish-black, with a yellow stripe on the mid-dorsal region. Their bodies are covered with spines.
The Clymene moth is said to have immense spiritual symbolism. The name Clymene holds great significance in Greek mythology, as it was the name of many people like a Cretan princess, a water nymph, an Orchomenian princess, and so on. Moreover, the wings form a pattern similar to the Holy Cross, especially when closed. Thus, seeing these moths is considered a good omen and a blessing indeed. -

Northern shrimp are protandrous hermaphrodites – they begin life as males and sexually mature at roughly 2½ years old. They transform to females at about 3½ years old. They start spawning in late July in offshore waters, mainly in deep mud basins in the southwestern Gulf of Maine. By early fall, most adult females have pushed their eggs out onto their abdomen. They prey on plankton (tiny floating plants and animals) and bottom-dwelling invertebrates.
Northern shrimp are found in the cold waters of the North Atlantic, North Pacific, and Arctic Oceans. On the U.S. Atlantic coast, northern shrimp are mainly found in waters off of Maine, New Hampshire, and Massachusetts.
Fishermen mainly use otter trawls to harvest northern shrimp, although some Maine fishermen use traps. Northern shrimp are harvested over soft mud bottoms, which are more resilient to the impacts of trawling compared to structured habitats such as corals. Also, the small mesh in the shrimp otter trawls creates more drag than a groundfish net and can’t be towed as fast for the same size net, reducing the potential impact on shrimp habitat. -

Executioner wasps are a species of social wasp found in Central and South America, mostly being spotted in Mexico, Paraguay, Argentina, and Brazil. Though they’re not commonly found in the United States, they are sometimes discovered in Texas.
Nicknamed the King of Sting, the executioner wasp is considered the most venomous wasp in the world with the most painful sting of them all. The pain encountered once stung is due to the histamine (inflammation, dilates blood vessels, affects muscle contractions) and norepinephrines (increases heart rate) properties in their venom that break down living cells and tissues around the sting site. It has a near unparalleled burning and throbbing sensation that can leave the effected area swollen and painful for days following the initial sting. Chances are, you would be okay if you got stung. But, if you’re allergic to insect stings, or if you’re a child or elderly individual, this would be one of the very worst insects to get stung by and it could certainly lead to your death.
Executioner wasps mainly feed on caterpillars before they turn into moths and butterflies. This gnarly insect often times decapitates its prey, much like that of a praying mantis.
They have an impressive longevity to them, generally living between 6-and-18 months, which is just astounding when considering the lifespan of other insects. -

The spider species Phrynarachne ceylonica, commonly known as Bird-dung Crab Spider, belongs to the genus Phrynarachne, in the family Thomisidae.
This spider has one of the most effective camouflages of all animals; its body is covered on blobs and warts that give it the appearance of a fresh piece of bird excrement; it often produces a small thread of white silk and sits on it so that it looks like the white stains caused by bird droppings falling onto leaves. And as if this was not amazing enough, it also smells like poop. This camouflage has a double function; it makes the spider a rather unappetizing prey for most animals (especially birds themselves), and it serves as a lure for the small, excrement-loving insects which are the spider’s favorite prey. These spiders are found in Asia, from Indonesia to Japan.
“Birds, almost all with good eyesight, will not go for what appears to be their own turd for food,” says Joseph K.H. Koh of the Lee Kong Chian Natural History Museum in Singapore.
The spider’s body has a glossy surface that gives it a “wet” look of fresh faeces, says Koh. “The nodules on the body and rough-edges of the legs further reinforce the ‘shitty’ look – pardon the rudeness,” he says.
When the spider moves, the illusion disintegrates. “The ‘walking poop’ no longer looks like a piece of dropping, especially with its legs spread out,” Koh says. -

🚨 ARTHROPOD OF THE DAY 🚨
Achrioptera fallax is a stick insect species found in Madagascar.
The males are a bright electric blue (with greenish tints) and have two rows of reddish orange spines along the edges of the femur. There are also dark colored spines going along the sides and underneath the thorax. Males are brachypterous (incapable of flight) and have small reduced wings. The forewings are a bright yellow; the hind wings have a yellow ridge and are primarily red with a black center.
The 7th and 8th tergum (abdominal segments) both extend outwards along the sides, giving it the gradual shape of a hexagon. The 9th tergite is like the rest of the abdomen but has a pair of cerci for mating. Cerci are like claspers (as seen in dragonflies) that help the male grasp the female during copulation. Females have a duller coloration. They are a light brown with red spines covering the entire thorax, as well as the top of the head, where males lack spines. -

The blue-fronted dancer (Argia apicalis) is a species of damselfly in the family Coenagrionidae, native to parts of North America. This damselfly ranges in length between about 33 and 40 mm (1.3 and 1.6 in). Most males have a blue thorax, the plates being separated by a few black lines, and also have a color-tipped abdomen, segments eight, nine and ten being bright blue. The remaining segments are dark brown. However the color of the thorax of Argia apicalis is variable and some males can be greyish-black rather than blue. They can change from one phase to the other and back again over the course of several days, with several intervening variations on the way; neither color phase seems to be particularly related to age or sexual maturity.
Adults are on the wing from mid-summer onwards. Males often patrol small territories over water but females only visit water when ready to mate. Copulation soon follows the arrival of the female, and the pair flies around the pond in tandem, investigating sites for egg-laying. The female begins ovipositing while still linked to the male and often continues to lay after he has flown off. The eggs are laid in mats of willow roots, among floating driftwood, on bits of floating board and on living, but horizontal, Helenium stems. By this time, the male is no longer aggressive towards other males, and several females use the same sites for egg deposition. -

Dictyopharidae is the 6th largest family of planthoppers worldwide, with 156 genera and 720 species at present (Bourgoin 2016). Dictyopharidae is represented north of Mexico by 14 genera and 85 species. The southwest includes nearly all species known from the contiguous United States.
Dictyopharids feed on a variety of plants with adults and nymphs both found on above-ground portions of plants. Most species are associated with dicots in a variety of plant families, and are most often reported as monophagous (Wilson et al. 1994).
The species seen in these images is nicknamed the cross-eyed planthopper, and is listed as found in Indonesia.
> In the time between hatching and becoming full-grown adults, tiny planthopper nymphs put on a flashy show. The planthoppers can secrete a waxy substance from their abdomen that results in strange, fiber optic-like tails. These decorations serve at least two purposes: to encourage predators to "ooh, ahh" instead of eating them, and to help them glide as they fall. -

Also called crab lice or “crabs,” pubic lice are parasitic insects found primarily in the pubic or genital area of humans. Pubic lice infestation is found worldwide and occurs in all races, ethnic groups, and levels of society.
The adult pubic louse resembles a miniature crab when viewed through a strong magnifying glass. Pubic lice have six legs; their two front legs are very large and look like the pincher claws of a crab. This is how they got the nickname “crabs.” Pubic lice are tan to grayish-white in color. Females lay nits and are usually larger than males. To live, lice must feed on blood. If the louse falls off a person, it dies within 1–2 days.
Pubic lice move by crawling, because they cannot hop or fly. They usually spread through sexual contact. Occasionally, they may spread through physical contact with a person who has pubic lice, or through contact with clothing, beds, bed linens, or towels that were used by a person with pubic lice. You cannot get pubic lice from animals. -

The dragon mantis (Stenophylla lobivertex) is a rare, leaf-mimicking insect found in the rainforests of Ecuador and Peru that measures about 1.6 inches long. This species’ name comes from its flattened body that looks like a dragon.
Its wings, unlike other mantids, are transparent enough to let sun rays pass through. They are mostly gray-green in color, with distinctive bright yellow markings and a mottled body that changes from pale green to light brown.
Despite their small size, Stenophylla lobivertex are quite active creatures and are characterized by their fast movements. They have short legs that squeeze together at different angles and a long, curved abdomen. They also have powerful forelegs that are serrated and end in a pincer-like shape, which they use to grab and hold onto prey.
Dragon Mantises have large compound eyes that are surrounded by a fringe of small spines.They also have three simple eyes, two located above their compound eyes and one on the top of their head.When disturbed, the Dragon Mantis spreads its wings wide and turns bright shades of yellow and green.It can also extend its rear legs to make itself look larger, as a defense mechanism against predators. -

At 8 to 11 millimeters in length, jagged ambush bugs (Phymata species) are small and mighty garden predators. Adults have an angular, greenish yellow, white, and brown bodies with small wings that leave the jagged sides of their abdomens exposed. Their forelegs are thickened with muscles and resemble the raptors of a praying mantis; like mantids, those legs are used to snatch and hold prey. Ambush bugs have short beaks that pierce into their prey and secrete saliva to dissolve the insect’s internal organs. The final segment of their antennae is slightly clubbed.
Jagged ambush bugs can be found throughout North America in southern Canada, most of the United States, and northern Mexico. They can often be seen in open meadows and gardens on the flowers of prairie plants like goldenrod and aster, where their body coloring will keep them hidden from potential prey.
Although smaller than their wheel and assassin bug cousins in the Reduviidae family, jagged ambush bugs are still voracious predators. As the name implies, they ambush their prey by sitting motionless and waiting for the right insect to pass by. These can be flies, small moths, beetle larvae, and other soft-bodied true bugs who are attracted to the plants the Phymata species sit on. They are also capable of catching prey much larger than themselves like bumble bees and butterflies. -

Thunder flies or thrips, or thripids as they're also known, are small black insects with long bodies and stings in their tails, which they use to puncture plants and other insects they consume. Thunder flies can be annoying in your house and yard because they destroy your garden plants and food.
Thrips are small hemimetabolic insects with a distinctive cigar-shaped body plan. They are elongated with transversely constricted bodies. They range in size from 0.5 to 14 mm (0.02 to 0.55 in) in length for the larger predatory thrips, but most thrips are about 1 mm in length. Flight-capable thrips have two similar, strap-like pairs of wings with a fringe of bristles. The wings are folded back over the body at rest. Their legs usually end in two tarsal segments with a bladder-like structure known as an "arolium" at the pretarsus. This structure can be everted by means of hemolymph pressure, enabling the insect to walk on vertical surfaces. They have compound eyes consisting of a small number of ommatidia and three ocelli or simple eyes on the head. -

The Christmas Island red crab (Gecarcoidea natalis) is a land crab famous for its epic annual mass migration to the sea to spawn.
Christmas Island red crabs are large crabs with bodies measuring 4.6 inches in width. Males tend to be larger than females, with larger claws and a narrower abdomens. They have claws of equal size, unless one has been damaged and has regenerated. The crabs are usually bright red, but orange or purple crabs sometimes occur.
The crabs are omnivorous scavengers. They feed on fruit, seedlings, fallen leaves, flowers, human rubbish, the giant African land snail, and dead animals. They also cannibalize other Christmas Island red crabs.
Christmas Island red crabs reach sexual maturity around 4 and 5 years of age. At the beginning of the rainy season (October to November), the crabs increase activity and travel to the coast for spawning. The timing is linked to the phase of the moon. -

🚨 ARTHROPOD OF THE DAY 🚨
Blister beetles are beetles of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematically colored, announcing their toxicity to would-be predators.
Unlike some insects, blister beetles don’t have stingers, nor are their jaws strong enough to break human skin.
The welts or blisters on your skin are a reaction to cantharidin, an odorless, colorless chemical the beetle releases to protect itself against its enemies.
Although cantharidin is highly toxic and dangerous to a blister beetle’s enemies, it’s not toxic to human skin. Contact with the substance, however, can cause a local reaction.
