About Calopteron discrepans (Newman, 1838)
Calopteron beetles show subtle variations in appearance, and three distinct species of this genus have been identified in North America and northern Mexico. Two of these species, Calopteron discrepans and Calopteron reticulatum, are very similar in external morphology. Their nearly identical appearance, combined with inherent individual variability, makes it challenging to tell the two species apart. However, subtle, reliable distinguishing features can be found primarily in the coloration of the metasternum and the second antennal segment, which are key traits for identifying this species. Calopteron discrepans, commonly called the banded net-winged beetle, is distributed across the eastern United States. Its range extends from New England in the north, south to Florida, and west to Oklahoma and Kansas. More recently, individuals of this species have been discovered as far north as Manitoba and Quebec, which expands its confirmed geographical range. Larvae of Calopteron discrepans live mainly in various microhabitats within their preferred ecosystem of moist woods. They are most commonly found in rotten logs, under loose bark, in soil, or in leaf litter. These habitats offer the best conditions for larval development and survival, providing plenty of food and a suitable substrate for pupation.
