I continue to find insects in Costa Rica to be so interesting and sometimes weird! And I quickly gave up on using a close up lens for insects because to get as close as is needed you scare off the bug! :-) Thus I use the same lens that I use for birds high in a tree, my 150-600 mm zoom lens and can get images sometimes nearly as good as a close up without scaring of the insect off.
One of those, besides the many butterflies that I prefer, was this blue and gray wasp with an fun face! enjoy these two shots and I have no good way to identify for sure, but think “Blue & Gray Wasp” is a pretty good temporary name for this one! And I searched several websites without finding this one out of hundreds of species here! :-)
