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 Polioptilidae: A family of passerine birds commonly known as "Gnatcatchers". All gnatcatchers are native to the New World, being found in both North and South America. Gnatcatchers are close relatives of the wrens and some species are known as "Gnatwrens".

Mansonella perstans

…is a species of Spirurid nematode that is widespread in parts of sub-Saharan Africa, Central and South America, and the Caribbean. M.perstans typically parasitizes humans and is usually contracted via a biting midge (usually of the genus Culicoides). Once M.perstans enters the body cavity they will begin to develop into adults. Once they mature they will start to mate and produce microfilariae that will enter the bloodstream. A midge will then ingest them it bites a human. After ingestion the microfilariae will move to the midge’s thoratic muscles and will develop into second and third-stage larvae. The third-stage larvae will move to the midge’s proboscis and will infect a human when the midge bites one.
