Cedar beetle

Cedar beetle

Sandalus niger

A species of Sandalus, Also known as Black cicada parasite beetle

The cedar beetle (Sandalus niger) is a cicada parasite beetle, meaning that both the adults and larvae feed on types of cicadas. The males and females have very different appearances. The males are light brown with red, feathery antennae while the females just look like ordinary black beetles. They are really lazy bugs that stay motionless and do not fly unless on blind dates.

Habitat Preferences of Cedar beetle Through Different Life Stages
The eggs of cedar beetle are typically laid in the soil near host plants, where after hatching, the larvae attach to and feed off roots. As they mature, these grubs will dwell underground. Searching for these larvae requires digging carefully around host plants to unearth them. The pupae also form in the soil, thus requiring excavation near larval feeding areas, but they tend to be deeper compared to larvae. The adult cedar beetle emerges from the pupae and is commonly found on or near the same host plants, but above ground. They can be spotted by carefully observing plant leaves and stems during their active periods.

When is the Best Time to Observe Cedar beetle
The best time to find cedar beetle would depend on its life cycle with adults typically being more active during warmer months. Larval stages should be sought after during earlier stages of the season.

What is the Best Weather to Observe Cedar beetle
Warm and dry weather conditions are more favorable for locating cedar beetle, as these promote the activity of many insects including those in the order Coleoptera.

How and Where Can You Find Cedar beetle at Different Life Stages
Larva Since cedar beetle larvae live within the wood, look for them by examining dead or decaying trees, particularly those with soft or rotting wood. Inspect boreholes or sawdust around the tree base which can indicate their presence.
Pupal Finding cedar beetle pupae would involve carefully splitting open rotting wood where larvae are known to reside, as cedar beetle pupates within the wood before emerging as an adult.
Adult Cedar beetle adults often emerge from their pupal cases to feed on tree sap and can be found on or around trees that exhibit sap flows or wounds. Observing such trees, especially at dusk or during warm evenings, can increase the likelihood of spotting them.
