This orange assassin was hiding under a cluster of frostweed flowers; I had to do some yoga to get even these pics. I've turned the images upside down so that the bug is right-side up.
Pselliopus is a common genus of assassin bug family (Reduviidae), in the subfamily Harpactorinae. The genus is restricted to the New World, with 22 species described. Some species, such as Pselliopus barberi, are conspicuous because of their bright coloring and relatively large size. Some species of the genus are of interest as potential biological pest control agents.
