Hello Bugman, well, here are a few insects that I haven’t’ been able to identify. I was travelling through Colombia in January when I spotted these interesting bugs. If you can help me with these critters I’d be eternally grateful!
Happy Easter!

Dear Coral,
We know one of these images was left over from the last time you sent a submission, and we are going to request that in the future you please limit the images in one request to a single species, unless there is a very good reason to submit multiple species, like a predator/prey relationship or a mutually symbiotic relationship, or perhaps if they are closely related.  Though we question the term “spots” with relation to this lovely creature, your butterfly is
Dynamine postverta, commonly called the Four Spot Green Sailor which we learned on the Project Noah site.  We verified that identification on Learn About Butterflies where we also learned:  “Most Dynamine species have highly reflective bluish or greenish uppersides, often in combination with a dark apex and borders. Dynamine postverta is easily recognised by the group of 4 squarish dark spots on each forewing. The underside is similar to that of other Dynamine species, being white, marked with narrow bands of orange. In common with several other species there is also a pair of blue-centred submarginal ocelli on the underside hindwings.  Dynamine postverta ( previously known as D. mylitta ) is the commonest and most widespread member of the genus, being found throughout most tropical and subtropical areas of central and South America, from Mexico south to Argentina and Paraguay.”  We also learned:  “The butterflies are very active in hot sunny conditions, when they can be seen flying rapidly in zig-zag fashion, investigating along forest tracks. In the cooler temperatures of early morning they can often be found basking on foliage, usually with their wings held half-open.  Males visit dry river beds, and damp ground along sunlit forest tracks and roads. They habitually flick their wings open while moving about in a fairly erratic fashion as they probe for minerals on the ground.”  The Mexican subspecies is pictured on Butterflies of America.

Hi Daniel, Thank you so much for helping me with the identification of my butterflies!!! It’s so exciting to be finally able to name them!  Keep up the great work!
