Northern California walking stick? - Carausius morosus

Northern California walking stick? - Carausius morosus
Oakland, Alemeda County, California, USA
October 2, 2010
Size: Unknown...maybe 3"- 4"
A friend found this bug; not sure if it's injured and lost it's two front limbs or not (I have never seen a 4 legged bug). Apparently it has been motionless on this wall for nearly a week.


Stick Bug in Bay Area
My 20 month old son found one of these hanging about 2 feet off the ground on the open edge of a sliding glass door about a week ago. It looked inanimate. The two front legs are held tightly against its "torso." Then last night, at 2 AM, I found another one of these weird bugs hanging on the edge of a bathroom window, on the same side of the house. This is in the woods in Kensington, just north of Berkeley. They have impressive grasping strength with just those four legs.

Moved from ID Request.

It looks to be the Indian Wal
It looks to be the Indian Walkingstick (Carausius morosus). They have shown up in the wild in coastal southern and central California. If I'm correct I'm not sure how well adapted they would be to the Bay Area. People get them as pets and then release them when they get too many offspring to care for. You might want to take a specimen to you local Agricultural Commissioner's Office to have it submitted for identification. Its unlikely that CDFA would make an effort to eradicate another population, but it always nice to know how invasive species are adapting to our climate. They can do a lot of damage to ornamental shrubs and ivy.
