Banded Net-Winged Beetle (Calopteron discrepens)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Banded Net-Winged Beetle.

 Updated: 2/2/2018; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




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.

Note: 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 as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.




Beetle Anatomy
Graphic showing basic anatomy of a common North American Beetle insect
1
Antennae: Beetles have a pair of antennae on the head used as sensors.
2
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
3
Thorax: Holds the three pairs of legs as well as vital internal organs.
4
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
5
Wings: Appendages used for flying and kept under the elytra until needed.
6
Abdomen: Houses organs related to circulation, reproduction, and excretion.
7
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
