Morning Eric,

Always something new to discover.  I tried BugGuide but could not locate a match.  If the spider had redish stripes along its abdomen I'd say it was a Misumena vatia.  My second guess is a formosipes.  Think you can provide the correct scientific name for this crab spider.


Looks like another Mecaphesa species.  Can't ID them to species without a mature male or female specimen under a microscope, and even then you might have to dissect the genitalia.

Mecaphesa are "hairier" than other similar flower crab spiders, especially on the cephalothorax and abdomen.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
