Sap beetle

The sap beetles are a family (Nitidulidae) of beetles.

They are small (2â€"6 mm) ovoid, usually dull-coloured beetles, with knobbed antennae. Some have red or yellow spots or bands. They feed mainly on decaying vegetable matter, over-ripe fruit, and sap. There are a few pest species.

Common species include:

• the picnic beetle, Glischrochilus quadrisignatus
• the dusky sap beetle, Carpophilus lugubris
• the strawberry sap beetle, Stelidota geminata
