Natural Habitat

Soil, compost, leaf litter, lawns, and decaying wood; this specimen appears to be on exposed garden soil.

Diet & Feeding

Larvae commonly eat plant roots, decaying organic matter, or both, depending on species. Adults often feed on foliage, flowers, fruit, or dung.

Behavior Patterns

C-shaped, soft-bodied larvae live underground and pass through three larval stages before pupating in a soil cell. They are usually nocturnal or concealed during daylight and may surface after disturbance or heavy rain.

Risks & Benefits

Some species damage lawns, crops, and garden roots; others recycle organic matter and serve as important food for birds, mammals, and predatory insects. Identification to species requires clearer views of the head, legs, and terminal abdomen.
