| description |
This species has a reddish or brownish color pattern with parallel vertical orange/yellow bars on the vertex and a pale midline. The pronotum varies in color from yellowish-orange to reddish-brown; there are three circular pale spots along the anterior half of the pronotum. The scutellum is pale to dark, sometimes with dark lateral triangles. The face is brown or black, and the thoracic venter is pale except for a dark mesosternum. This is a variable species with three color forms. In the nominate form, the wings are largely a bold red color. There are three large white spots near the base of the wings, separated by a broad red clavical line. There are four smaller white spots clustered around a reddish triangle closer to the wing tips, forming a spade-like shape. The wing tips are blackish, sometimes relegated to an L-shaped line extending outwards on each tip. Form 'mallochi' resembles the nominate form but is paler overall, appearing faded. The third form 'repetita' looks quite different from the other two forms; it has three dark crossbands, one across the thorax and base of the wings, one across the middle of the wings, and another at the wing tips. Adults are 2.8 to 3.2 mm long. (Dmitriev & Dietrich, 2007) |
| distribution |
Central and eastern United States and southern Canada, west to the Rocky Mountains (3I); recent records (these from NC) seem to add this species to the Southeast and east of the Appalachians. |
| abundance |
Recorded recently from Vance and Warren counties in the upper Piedmont, constituting the first known records of this species in North Carolina; possibly more abundant across the state, especially where willows (Salix sp.) are present. |
| seasonal_occurrence | |
| habitat |
Brushy vegetation, likely where willows occur. |
| plant associates |
Salix myricoides, S. babylonica, S. cordata, S. bebbiana, S. petiolaris, S. caprea, S. humilis, S. interior (3I). Has been found in the state on black willow (Salix nigra). |
| behavior |
Can be attracted at night with a light. |
| comments |
Individuals of form 'repetita' could be confused with E. tricincta; however, the pattern in this form of E. rosa appears dirtier and less defined than in tricincta, where the pattern is cleaner. This species could also be confused with some individuals of E. elegans. However, the nominate form of E. rosa tends to have a more restrictive red pattern across the wings, and the white dorsal patch closer to the wing tips is a bit filled in, with less white than in E. elegans. |
