Hi, Joanne, and welcome to the forum!
I'm sure many of our members would be willing to help you, but it would make it easier if you would share some information about what part of the world you're in, or better yet, where the picture was taken. This is an international forum, and knowing the location would help to limit the number of species that have to be considered.
