I collected this specimen at 35°05'56.8"N 106°28'35.7"W, Alameda 7.5’ quadrangle, on a Alecea rosea (hollyhock) blossom. The serrated outer edge of the mesotibia identifies it as Ripiphorus rex.

This specimen as soaked in ethanol, then acetone, for at least 24 hrs. each, then rapidly dried with the intense light of a 250W dual fiber optic microscope illuminator to prevent shrivel.
