I often come across crab spiders (family Thomisidae) whenever I’m looking at flowers, and I’ve written about them twice before. Last fall I found one waiting for prey on a daisy fleabane, and last month I found one that had caught a flower fly on a cutleaf toothwort. The individual shown here was patiently waiting for a meal on a roughleaf dogwood (Cornus drummondii, Cornaceae). As with the other two spiders, I suspect this individual was of the genus Mecaphesa.
There were a lot of soldier beetles (family Cantharidae) crawling around on these flowers. One kept getting close to this spider, and I was holding my breath hoping to see the spider attack. The beetle moved on, however, and so did I.
