Necrorak

Necrorak are small Cheliceratas that resemble Black widow spiders in appearance. They live in groups, unlike most Cheliceratas, following the orders of their queen. They first appear in a recent Monster Hunter EX update.

Monster Hunter EX: Bio
Small spider like Cheliceratas that follow the orders of their queen. Alone, they are harmless, but in swarms, they are lethal! They use combined teamwork, and venomous bites to take down large prey and drag said prey to their nests to feed the hive.

Gojira57's notes

 * The teamwork between Necrorak is based on the fact that a certain species of insect, that as larvae, work together as they migrate, and often tap on tree branches, sending a sort of morse code to help those that get lost find their way to the group. I forgot which species, but I am sure you can figure it out.
 * The part where the Necrorak are living in groups mirrors the existence of Social spiders, which make a single nest together, and live together.
