Hi, I'm Andrew and I’m just a simple 19 year old guy and zoology student that posts random factoids about obscure animals and general animal science/zoology/biology stuff so if you like animals this is the place for you, if you only like cute animals this is not the place for you… Also I can ID any animals you might need identified (just submit them to me).

Disclamer: none of the pictures are mine unless stated

Family Callidulidae: An unusual family of moths known as "Old World Butterfly-moths. Callidulids are a family of butterfly like moths which are distributed throughout southeast Asia and Oceania. Callidulids can exhibit both day and night flying behavior and typically hold their wings over thier backs like butterflies. Thier closest relatives are know truly known but they are thought to be close to hook-tip and geometer moths.

Mermis nigrescens

…is a large species of parasitic mermithid nematode that is native to the nearctic and palearctic ecozones. M.nigrescens usually parasitize grasshoppers and are ingested as eggs. Once an egg enters a grasshopper the outer layers of the egg will rub off and the larvae will move out. Once hatched the larvae will pierce the gut wall and enter the body cavity where they will feed on body fluids. in 3-6 weeks the will emerge from the hosts, crawl into the soil, molt, and mate. Females will spend their winter in the soil and will emerge on rainy or dewy morning in spring/summer to climb up on plants and lay their eggs.
