Stick Insects Update (1 month)

sticky-4 Follow up to my first post on stick insects. Most of the insects are approximately a month old or so now and have gone through a couple of moults. As can be seen from the photo below they are growing (couldn’t find a 5p coin today, so a 20p was used, diameter 21.4mm) but still a long way to go. Gait patterns still seem to be stuck rigidly to the tripod gait. The jar is now starting to get a bit crowded, and changing the plants has become tricky (they’re fast little buggers when they want to be) so next week I will be upgrading their accommodation next week to one of the excellent BSP Cages from Small Life Supplies, one of which I have been using at home for a while now. This will also give them the necessary room to moult successfully, as well as making it easier to care for them. Photos follow:

  1. I am trying to identify a bug that is in my home. It is very similar to the ones in your pictures. I have a few pictures that I’d love to send to see if they are the same.

  2. Hi Jackie, the easiest way to identify stick insects is by their eggs, which adult ones lay frequently. Indian stick insects, which is the type I had (Carausius morosus) have eggs like those shown at
