Phyllobrotica
skeletonizing leaf beetles, flea beetles
Phyllobrotica is a genus of leaf beetles in the family Chrysomelidae, containing at least 18 described species in North America. Members are small, often brightly colored beetles known as skeletonizing leaf beetles and flea beetles. Most North American species are extreme host specialists, feeding almost exclusively on plants in the mint family (Lamiaceae), particularly genera Scutellaria and Stachys. One species, P. physostegiae, has been documented on Physostegia, representing an unusual host transfer to a related mint family genus in dry prairie habitats.
Phyllobrotica costipennis
skeletonizing leaf beetle
Phyllobrotica costipennis is a species of skeletonizing leaf beetle in the family Chrysomelidae. The species was described by George Henry Horn in 1893. It is recorded from North America, though specific details about its distribution, host plants, and biology remain poorly documented compared to congeners. Like other Phyllobrotica species, it likely exhibits strong host plant specialization.
