From the field notes
Diet
Despite their nickname, the 'potato bug,' they are rarely agricultural pests. They munch on roots, decaying plant matter, and dead insects they find while burrowing in the soil. They do their part in aerating the dirt and recycling dead organic matter.
Defense
These gentle giants would much rather hide than fight. If startled, they might raise their spiky back legs to look tough, emit a slightly sour smell, or give a strong nip with their powerful jaws.
Misnamed Critter
This insect is a double misnomer—it is neither a true cricket, nor is it native to Jerusalem. It is actually a wingless, nocturnal relative of the wētā, native to the western United States.
Communication
Since these insects are completely deaf and have no ears, they find mates in the dark underground by performing a rhythmic drumming ritual. They repeatedly strike their heavy abdomens against the dirt, sending seismic vibrations through the ground.
Field Marks
Its shiny, oversized, amber-colored head almost resembles a tiny, bald human face. It also has a boldly striped, plump abdomen and thick, spiky legs built for heavy digging.
