Subject: Beautiful blue/black wasp

This looks like a Blue Flower Wasp (Scolia soror) which is native to Australia but I’m not sure because I saw it in Jamaica. It also looks similar to Blue Mud Wasp (Chalybion californicum) and Blue Mud Dauber (Chlorion aerarium) and even Great Black Wasp (Sphex pensylvanicus). It doesn’t appear to have a narrow waist from the photos I took. It is so beautiful – I want to post it on our website and would love to know the correct name before posting.
Thank you for your assistance!

We agree with your initial impulse that this is a Flower Wasp in the family Scoliidae, and the Blue Flower Wasp that you cited is a member of a genus also found in the New World. BugGuide lists five species in North America, and notes that there are seven species reported from North America. The species on BugGuide that looks the most like your individual is Scolia mexicana, which is only listed from Arizona, but if its range extends into Mexico and Central America, it might actually be your species. Alas, the best we are able to do is speculate that it is a Scolia species.
