The intricately textured wings of the orange and black Banded Net-winged Beetle are said to resemble the flaxen nets used by fishermen.

Active in the daytime and at sundown, Banded Net-Winged Beetles are commonly spotted resting on flowers or leaves. They flare their elytra (wing covering) and wings open in a possible attempt to scare off a threat. Bright thick bands of orange and black alternate across the elytra. A raised textural pattern of lines covers elytra in a net-like fashion, informing this species' common name. The orange pronotum is rounded by the head, but comes to two long points on either side of the 'neck'. A black line runs down the middle pronotum.

Their pupae are less colorful. Brown and covered in ridges, the wingless juveniles have white extensions coming out their sides which makes them look similar to chubby centipedes. They are often grouped together on trees and stems in overlapping masses. They contain a chemical that makes them taste unpleasant to potential predators. Look for pupae in woods or forests near rotting logs and trees, and watch for adults on flowers in meadows and gardens.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
