Monday Night Mystery: The Case Of The Eight-Legged Hitchhikers



After a long hiatus, the Monday Mystery returns!

1. What is the genus of the big, colorful animal? (3 points)
2. What is the genus of its hitchhikers? (3 points)
3. This image is heavily cropped to better show the little hitchhikers, but the original exposure also captured a third arthropod. What was it (2 points), and how does it interact with the two species pictured here (2 points)?

The cumulative points winner across all mysteries for the month of February will win their choice of 1) any 8×10-sized print from my insect photography galleries, or 2) a guest post here on Myrmecos.

Good luck!

  1. 3. Probably carrion flies. Those mites eat the eggs and larvae of carrion flies. They take a ride carrion beetles, invade the a corpse and eat the fly eggs. It’s good for the beetle to carry these mites, because carrion flies are competitors for the corpse. This interactions equals more carrion left over for the beetle larvae. 🙂

  2. Yep. Nicrophorus with fly eating Poecilochirus mites. Third arthropod a fly larva/adult/pupa. The beetles carry the mites to fly sources (carrion).
