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.

Why do birds fly?
part 1: the trees down hypothesis
Well since you all know what the drive was for fish to move out of the water. I thought I would explain the two main thesis for the origin of flight in birds. It is now thought that feathers did not evolve for flight but for thermoregulation and/or display. So how did birds evolve then? well there’s two competing hypothesis the ground up and trees down hypothesis. I will focus on the latter for this post, in short the trees down hypothesis states that birds used their claws to climb up trees and then used proto-wings to glide to treetop to treetop like colugos and flying squirrels do today. From that birds developed better wings and gliding turned into flying and modern birds arose.
