The fly that tricks ants and who never grows up.
Imagine you run a nursery. You & your sisters care for many helpless babies. One day you notice a baby is... different. It never grows up. It's not a baby ant! It's an adult phorid fly! A fly without legs, or wings! Can you spot the fake?

This ant is not carrying a larvae but one of the phorid flies. She found it and is taking it to the nursery where it "belongs" We don't know the whole life cycle of this sneaky parasitic insect yet. It was only discovered in 1995 and there is much more research to be done!
Vestigipoda sp. trick army ants into taking care of them.
I cannot stress how WIERD it is that an *adult* fly is totally immobile & looks like a larvae of another species. (army ants in this case)
Under a microscope you can see the fly-like features of Vestigipoda's face. Incredible becoming totally "helpless" is such an effective adaptation. I really want to know what the entire life cycle is like. How do they mate? What are they like when they are maggots? Are they disappointed to be a maggot and pupate only to be a larvae?
(Listen, creepy fly... at least you don't need to do anything to find food. The ants clean you and take care of everything. )
