Soldier Beetles
Description & Overview
Soldier beetles (Cantharidae) are the second largest group in the beetle (Coleoptera) superfamily Elateroidea, containing approximatley 5,500 species [1]. Soldier beetle larvae tend to be darkly colored and look almost reptilian. Adult soldier beetles grow to about half of an inch long and are yellow to tan in color. Some abdominal segments are exposed, as their wings do not entirely cover their body. These insects are beneficial, as they mainly feed on nectar and act as a pollinator species [2].
Taxonomy
Ecology & Evolution
From midsummer to early fall soldier beetles tend to pollinate yellow flowers of the family Asteraceae. Adults soldier beetles feed exclusively on pollen [4].
Soldier beetle eggs are laid from late August to early September. Though soldier beetle life history is not well known, larvae are assumed to predate on small invertebrates within the soil. Some soldier beetles are able to produce compounds that help stave off predators, like spiders [4].
