Uncharismatic Fact of the Day

You know Dasher and Dancer, Prancer and Vixen, but do you recall... the reindeer wasp? Many species in the family Eucharitidae are noted for their unusual antennae, which branch out to resemble the antlers of a reindeer! But instead of toys for children, reindeer wasps lay eggs near ant hills. The larvae hitch a ride on in-going ants, and once inside, feast on the ant larvae in the nest until they're ready to pupate.

Galearia spp. are probably one the most ridiculous looking Eucharitid wasps I've ever seen. It is also a favourite. It looks like a weird spaceship or something. The first image is my drawing, the second image is a reference photo from the above provided link. Galearia (i) is pictured at the bottom left.

it's time to look at eucharitid wasps and appreciate just how shaped a beast can be

the working theory as to why so many have those big weird spines is that since they're often parasitoids of ants, they use the spines to protect their wings from the tunnel sides when the newly emerged adult crawls out of the ant nest
