Species haematites (Grammoptera haematites)

Explanation of Names

Grammoptera haematites (Newman 1841)

haemato - Greek 'blood'(1)

Size

4-7 mm(2)

Identification

Typical form has dark elytra, orange pronotum and front femora. Yanega (2) notes "head is black except for the clypeus, and the basal antennal segments and legs are mostly reddish (scape reddish beneath)". That source also notes the pale hairs on elytra and pronotum.

The dark form (below) is often confused with G. subargentata (see comment here). The dark form appears to be more common in northern populations (2).

Range

e. N. Amer. - Map (3)

Season

Apr-Jul(2)

Food

Larvae feed on various shrubs(2)

Remarks

Perhaps a Batesian mimic of Oedemeridae (False Blister Beetles), such as Asclera:

Oedemeridae are known to have strong chemical defenses, including cantharidin (4).
