The kids stick insects are growing, and one of them has changed! They were all green a week ago and then yesterday the kids exclaimed quite surprisedly that there was a strange brown insect in the cage. It turned out to be one of the others but changed!
It is pretty cool and we think it is a children's stick insect, but we aren't quite sure. We also think that it is male due to the longer wing case on it's back.
The photo doesn't show up it's colours too well but it is very pretty!
We think the other two, one of them the same size as the brown one, are a male/female pair. Hopefully the kids will be able to breed stick insects!
