Explanation of Names
Helopini Latreille 1802
Numbers
44 described spp. in 3 genera in our area(1) (all in the subtribe Helopina); 2-3 subtribes total
Identification
A notable field character is the distinctive death-feint posture, with antennae held parallel and forwardly outstretched while legs are held tightly against the body(1)
Range
primarily throughout the Northern Hemisphere (north temperate to tropical regions); in our area, most spp. in sw. US, and only 11 east of the Mississippi River(1)
Habitat
During the day, beetles hide under leaf litter and fallen wood at the bases of trees, and appear to be most common in well-drained sites with minimal humus depth and often with moss patches on the ground around trees. They may also hide under loose bark of dead standing wood; larvae and pupae in the soil(1)
Season
adults do not survive a full year but may emerge during warmer winter periods (Dec-Mar) in the so. Coastal Plain(1)
Food
Adults have been observed feeding on lichens on tree trunks at night(1)
Life Cycle
probably univoltine(1)
Remarks
Adults can be collected in numbers on trees at dark, primarily in spring and early summer(1)
