Alydus eurinus is a species of
Morphology
Alydus eurinus is mostly dark in color with lighter markings sometimes observed on the legs and abdomen. However, coloring on the side of the head is absent. Fine hairs cover the body. The corners of the posterior pronotum plate are rounded, while in a similar species, Alydus pilosulus, the corners are more angular.[5] Their wings are dark in color and possess many longitudinal veins, which distinguish them from the morphologically similar family, Lygaeidae.[6]
Sound production
Alydus uses ridges, or
Diet
Alydus eurinus feeds mostly on legumes but can be found on flowering plants, such as goldenrod, later in the season.[6]
Defense
The primary defense is mimicry. As nymphs, they resemble flightless ants. As adults, they resemble spider wasps.[8][6] Unlike ants and wasps, Alydus eurinus has mouthparts typical of the Hemipteran, in which the mandibles and maxillae have been modified to form a stomatostyle.
They also have a secondary chemical defense. The defensive chemical mix of butyric and hexanoic acids is released from their metathoracic scent glands.[8] Nymphs and adults possess defensive chemicals, but the Nymph's chemical mix is much weaker than the chemicals the adults produce.[6]
