Adult Flea Beetle Feeding Damage Mature larvae are about 3 mm long. Larvae are white, with a shiny, pale-brown head and three pairs of legs. They appear slender and worm-like.  Adults are about 2 mm long, elongate-oval, with brownish-yellow bodies and darker, reddish-brown heads.  The hind legs are long and thickened for jumping, hence the name "flea beetle". Mint flea beetle overwinters as eggs in the soil near the crown of mint. Eggs hatch in early April through early May.  Development is completed during late May and early June. Larvae pupate in the soil. Adults emerge in early July and begin laying eggs about three weeks later. There is one generaion each year.
