Flea beetle - Wikipedia
Adult flea beetles feed externally on plants, eating the surface of the leaves, stems and petals. Under heavy feeding the small round holes caused by an individual flea beetle's feeding may coalesce into larger areas of damage. Some flea beetle larvae (e.g. …

Adult flea beetles become active in early spring. Depending on the species, females lay single or clusters of eggs in small holes, in roots, soil, or leaves of many vegetables as well as occasionally on flowers and ornamental shrubs and trees. Small white larvae hatch from eggs and feed on the roots of the newly planted seedlings.

Larvae: The larvae emerge 5 to 8 days after oviposition (egg laying) (Konstantinov and Vandenberg 1996). The larvae hatch and feed on the leaves of their host plants. The larvae appear dark brown to black, and average 5.2 mm (0.2 inches) in length. The larvae have 10 body segments, with three pairs of small legs near the head (Lee and Shim 2003).

Flea beetles lay their eggs on plants or in soil around the base of plants. The tiny larvae feed on the roots of the plant, doing only minor damage to edible crops. Generally, flea beetles are not difficult to control, but often they will have already seriously injured crops before they are detected or the extent of damage is realized.
Flea beetles - Agricultural Biology
The appearance of larvae depends on the life history of the species; larvae that feed on roots are small, pale, and worm-like with a brown head capsule, while those that feed on foliage are black or gray and have small legs.

Larva: Small, white, and worm-like with a brown head. Pupa: Small and cream to white; pupate in the soil. Flea beetles overwinter as adults in protected areas under soil clods, plant debris, and weeds. They emerge from overwintering sites in mid- to late- spring and mated females lay eggs in the soil at the base of host plants.
Young stages (larvae) of most flea beetles feed on the roots but some develop chewing leaves. Young plants and seedlings are particularly susceptible to flea beetle damage. Growth may be seriously retarded and in severe infestations plants can be killed.

Larvae feed on the roots and tubers of susceptible plants but don’t often cause economic damage. Larvae of the horseradish flea beetle also mine the stem and leaf veins. In addition, many are vectors of plant pathogens. Flea beetles overwinter as adults in …
Flea beetle | Description, Insect, Pests, Crop Damage, & Control ...
Flea beetles are important pests of cultivated plants: the adults feed on the leaves and the larvae on the roots. Some flea beetles carry plant diseases such as early potato blight. They are unrelated to true fleas. Flea beetles are tiny beetles, usually less than 6 mm (0.25 inch) in length, and are often dark or metallic in color.
