Glue Maker

Here's my glue maker...This subterranean insectoid-crustacean uses its spit which is essentially glue to form an underground chamber and nest. The creature leaves the roof of the chamber weak so that any prey that walks over the hardened saliva will fall through. Once the creature is triggered by the falling victim it releases a thick ropey load of glue that ensnares the prey and hardens... the beast can then dine at leisure, hanging the leftovers for later consumption.
