Hyalymenus sp.

Broad-headed Bugs

Hyalymenus sp., Broad-headed Bug eating

Family: Alydidae

Subfamily: Alydinae

Length: typically 15 - 19 mm in the genus



In Hyalymenus as in other genera of this family, the nymphs resemble ants, while the adults look like typical true bugs. The nymphs enhance their physical resemblance by zig-zag walking, constant agitation of the antennae, and spending time in the company of ants. The nymphs appear to practice Batesian mimicry, and are thus able to avoid predators that avoid ants.
