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.

Dog Hookworm (Ancylostoma caninum)

….a species of hookworm restricted to temperate, tropical and sub-tropical regions worldwide. A.caninum typically infect dogs and other canids and can cause serious damage. Like other hookworms A.caninum is transmitted via feces, as the larvae grow there. If the larvae gain contact with a host they will penetrate the skin and make their way to the lungs. Once in the lungs they will ascend into pharynx and are swallowed. They will settle in the lower intestine, where they will attach to the intestinal wall and mature into adults. Eventually they will mate and their eggs will leave the body via excrement.

Dog hookworms can cause major damage to the intestines and should be treated if contracted.
