The Cedar Beetle does not attack its namesake. It actually prefers to hunt the grubs of Cicadas before they mature.





The Cedar Beetle has a parasitic relationship with Cicada larvae. Female beetles lay their eggs on trees so sightings of them on trunks may cause one to think they are actually attacking the tree like other beetles (i.e. the Asian Longhorn Beetle). The Cedar Beetle's eggs hatch and the larvae burrow into the ground, searching for young Cicada grubs or nymphs buried there. The beetle larva will attach itself to the Cicada larva and slowly eat through its exterior and into the insect, eventually killing it.

Cedar Beetles appear completely black from overhead, but the abdomen, hidden by wing coverings, is orange. The abdomen is usually only visible when the beetle spreads its wings. Ridges on the elytra give it texture. They have fan-like tips at the end of their antennae. They may increase surface area, which could help collect more information about the environment and surroundings. They are active during the day, and when in flight, may be mistaken for fireflies.

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.


Territorial Reach (A-to-Z)
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 below as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections below 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.

Territorial Area Map (Visual Reference Guide)
The map below showcases (in red) the states and territories of North America where the Cedar Beetle may be found (but is not limited to). This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan. Some species are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America.
