Diapheromera femorata, the Northern Walking Stick

Myrmecos blog commentators identified Sunday’s mystery photo almost instantly as a stick insect laying an egg. The species is the Northern Walking Stick Diapheromera femorata, a common local insect easily collected by beating tree branches. We’ve taken a few home as pets, and the females are obligingly dropping several eggs a day.

The eggs of D. femorata resemble plant seeds

What is its myrmecolgical importance? Are the eggs carried to the nest by harvester ants?

  The eggs have an operculum that attracts ants, so the ants disperse the eggs. This is analogous to the elaiosome of ant-dispersed plant seeds.

Great shots! I love these guys. I’m sorry to say the last one I saw was being dismembered by a rather upset Polistes annularis.
