After a bumpy ride to Florida and some setbacks including a flat tire, driving winds, and finger lightning, it was finally time to gear up and go on a night time hunt for bugs. As we entered the woods, familiar figures greeted us; Cariblatta crawled up the trees and Parcoblatta froze in our headlamps. Alan and I had stopped to admire a mating pair of Virginia wood roaches, and I continued observing them while annotating and recording. Alan had decided to check the other side of the tree, which was clearly a good choice; the next thing I heard was a stuttering mix of “WHOOOAA!”s and “WHAAA?”s. Satchell soon chimed in with a “What in God’s name…”. I directed my attention to where all the headlamps were convening; sitting comfortably on the side of the log was the largest cave cricket I had ever seen. Easily over 90 millimeters long (not including the antennae), the monster has forever wrecked my view of the smaller, diminutive cave crickets I had encountered in Michigan. It was not the first of its kind to greet us that night; many others soon followed, some smaller and some even larger. Out of fifteen or so individuals I collected, only seven or so survived the week-long road trip through the rest of Florida and all the way back up here to the frigid north. However, once they had adjusted to their new enclosure, the species bred steadily. In fact, though many adults died suspiciously prematurely (most likely due to parasites remaining in their system from the wild), one female that was collected as an adult during the trip survived an additional six months despite losing both of her back legs. Her offspring will be the captive ambassadors for this novel and freakishly impressive species.

The slender-legged cave cricket ranges through the southern and eastern US, however this colossal variety is believed to be endemic to a small area around the Apalachicola River in Florida. Its sprawling gait and long, stiff antennae give it excellent tactile senses. Nymphs of this species will accumulate on vertical pieces of bark, and they will bunch together so closely that they appear to be one homogenous blob of legs, bodies and antennae. Cannibalism has not been a problem with this species, with all life stages cohabitating happily. Handling is a unique experience: adults will casually perch on hands but will spring several feet away if disturbed.
