Arthropod of yesterday I forgot to post it here:
The western pygmy blue (Brephidium exilis or Brephidium exile) is one of the smallest butterflies in the world and the smallest in North America. It has reached Hawaii, as well as the Persian Gulf, including eastern Saudi Arabia, Bahrain and the United Arab Emirates.
Males establish a territory in which they look for receptive females to mate with. After mating, females lay eggs on all parts of the host plant, oftenmost on the uppersides of leaves. The caterpillars eat all parts of the plant; host species include Pigweed (Chenopodium album), saltbush species (Atriplex), and others in the goosefoot family (Chenopodiaceae). Adult imagos appear in July–September in the north, while it appears year round in South Texas. Adults feed on nectar only.
