Niña de la Tierra: Children of the Earth

No it's not the title of a horror film, Children of the Earth is actually one of the many common names for Stenopelmatus fuscus. Other names lovingly given to this insect are Jerusalem Cricket, Potato Bug, Skull Insect, and my personal favorite, Devil's Baby!

Earlier this week Sam Easterson found one in his front yard and captured this picture and footage.

Are you Looking at Me?

These crickets are very common in Los Angeles. Consequently, my colleague Brian Brown, the Museum's Curator of Entomology, and I get calls about them all the time. I most often get calls after heavy rains, when these crickets come up from the depths of their soily abodes. They are stellar diggers (Check out their fossorial front legs, modified for digging) and live most of the summer months deep underground to escape the heat. Aside from their enlarged digging legs, their most obvious feature is their highly-domed head, which gives them an alien-like look. To continue the alien theme, these large heads contains multiple "brains!" To be scientifically correct they are actually cerebral ganglia, or masses of nerve tissue, which control the action of the chewing mouthparts, eyes, and antennae. Maybe I should propose a new name for this cricket, Alien's Devil Child?
