Reader Robert Lang made a trip to Costa Rica earlier this year, and sent some photos of arthropods. His captions are indented:
We saw fewer arthropods (other than butterflies) than I expected in the various wet forest environments, but the ones we did see were quite spectacular.The Blue Land Crab (Cardisoma guanhumi) was shot near the Caribbean coast.
The Golden Orb Weaver (Nephila clavipes) was fairly common. The guide called it a “golden oar” spider, because the wide parts of the legs looked like oars, he said. This is a female, about 5 inch leg spread. If you look closely, you can see the male just above, trying not to get eaten.
The Orange-Kneed Tarantula (Megaphobema mesomelas) was coaxed out of its burrow at night by wiggling a twig near the entrance to simulate prey. The tarantula was not happy being fooled.
The scorpion (unidentified species) was interesting because it had all its babies hitching a ride on its back.
The walking stick (unidentified species) was about 9” long. The guide pointed it out on a night walk, and even looking right at it, it was hard to identify as what it is. To add to the illusion, it held its forelegs and antennae out straight, inline with the body. Eventually, though, it relaxed, as here.
