Have been told it is a Chrysomelidae and from the Cassida species.Never came across one myself.
Have look here http://www.biopix.com/family.asp?catego ... ysomelidae
What particular group of insects you are really fond of?
I think you are right it does look like Cassid vittata, but I am only a self-taught amateur, so take that with a pinch of salt,
My favourites are draonflies and butterflies.
I do have images of insects which are not represented on your fauna page, and since you are going to update this you might want to include some of these as well. If you agree we can meet and you could select the ones you want.
