Fly fact of the day: Some adult flies produce silk.
Silk is a very common protein fiber to produce, shared by a lot of arthropods, so I'm not so surprised when I learn of another insect that can produce it.
But still, it's pretty cool.
Some male flies in family Empidae wrap gifts for females in silk produced in their legs.
