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.

How do certain invertebrates know if they are rightside up?

the science of statocysts 

certain types of invertebrates like bivalves,echinoderms and cnidarians lack sensory receptors, buy yet they know if they are upside down or not and can right themselves up if knocked over. This is due to a special balance sensory receptor called a statocyst, a statocyst can be easily described as a marble inside a basketball, as the statocyst consists of a sac-like structure with a small ball-like mass inside of it called a statolith. The walls of this fluid filled sac are lined with small setae (hairlike structures). Which when the animal moves or is overturned the statolith inside the sac will respond to gravity and fall into the hairs which in turn will activate neurons that tell the animal what orientation it is in so it can adjust accordingly.
