| description |
A species with a robust, short head and a shining black coloration. Adults are brachypterous, meaning they have short wings. The pronotum and abdomen are also short (abdomen is inflated in females), with the pronotum being three times as wide as long. Rarely does this species have macropterous, long-winged adults. The eyes are black with silver-speckles, and the legs are orange with dark feet. The female pregenital sternite is broadly and convexly rounded. The male subgenital plates have the outer margins convexly rounded to bluntly-tipped apices. Adults are 3 to 4 mm long. (Lawson, 1920; DeLong, 1948)
There is a uniformly reddish-brown form with the last segment of the abdomen and ovipositor dark, and the eyes and ocelli dark too. This form is known as D. gammaroides var. fulva and primarily occurs in the western and central U.S. (Lawson, 1920)
Another form, D. gammaroides var. flava, has a black vertex, pronotum and basal section of the abdomen, but the wings and final two or three segments of the abdomen are yellow (DeLong, 1948). |
