Trirhabda attenuata
skeletonizing leaf beetle
Trirhabda attenuata is a skeletonizing leaf beetle in the family Chrysomelidae, distributed across North America. The species is one of several in the genus Trirhabda, which are known for their specialized feeding on particular host plants. Like congeners, it exhibits the characteristic skeletonizing feeding pattern of removing leaf tissue between veins. The species was described by Thomas Say in 1824.
Trirhabda borealis
Boreal Goldenrod Leaf Beetle
Trirhabda borealis is a skeletonizing leaf beetle in the family Chrysomelidae. It is a specialist herbivore associated with goldenrod (Solidago) and has been studied for its movement behavior in fragmented versus continuous habitats. The species occurs in North America, with records from western Canada and the northern United States.
Trirhabda diducta
skeletonizing leaf beetle
Trirhabda diducta is a species of skeletonizing leaf beetle in the family Chrysomelidae, first described by George Henry Horn in 1893. The genus Trirhabda comprises approximately 26 North American species, most of which are associated with goldenrod (Solidago) and related Asteraceae hosts. Like congeners, T. diducta is expected to be a specialist herbivore with larvae that mine leaves and adults that skeletonize foliage. The species occurs across North America, though specific host associations and detailed biology remain poorly documented compared to better-studied relatives such as T. canadensis and T. virgata.
Trirhabda manisi
Trirhabda manisi is a species of skeletonizing leaf beetle in the family Chrysomelidae, first described by Hogue in 1971. Like other members of the genus Trirhabda, it is expected to feed on leaves of specific host plants, skeletonizing the tissue between the veins. The species is known from North America, though specific details about its biology and distribution remain poorly documented. It is one of approximately 30 species in the genus Trirhabda, most of which are associated with Asteraceae host plants.
Trirhabda nitidicollis
Rabbitbrush Beetle, Rabbitbrush Leaf Beetle
Trirhabda nitidicollis is a species of skeletonizing leaf beetle in the family Chrysomelidae. It is found in western North America, where adults feed on rabbitbrush (Ericameria nauseosa). The species is commonly encountered in pinyon-juniper woodland habitats during summer months.
