Flea beetle (likely)

Vegetation, leaf litter, gardens, and agricultural fields; adults may occasionally wander indoors. The image is insufficient for species-level identification.

Adults chew small holes in leaves, especially brassicas and other herbaceous plants; larvae typically feed on roots or underground plant parts.

Small, dark, often shiny beetles that jump strongly when disturbed using enlarged hind legs. Adults commonly appear in spring and summer and may overwinter in plant debris or soil.

Generally harmless to people and pets, with no meaningful biting or disease risk. Some species are crop pests, while others contribute to food webs and decomposition.
