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
