Construction of the Imago
The abdomen measures between 32 and 34 millimeters in Rhodopygia pruinosa males. In females, it is only slightly shorter and measures 30 to 31 millimeters. While this part of the body is red in males, it is brownish in females. The thorax , however, is brown in both sexes. With age, the thorax and abdomen of males appear increasingly pollinated (“pruinose”), which is where the name pruinosa comes from. This discoloration is less pronounced in females. The face is greenish brown. The hind wings measure about 40 millimeters in both sexes. The dark brown wing mark ( pterostigma ) is 4.0 millimeters larger in the females than the 3.4 to 3.9 millimeter mark in the males.

Young animals in particular are easy to confuse with Rhodopygia cardinalis . Only the appearance of pollination makes the distinction easy.
