Guides
Brachyleptura brevis
Short Long-horned Beetle
Brachyleptura brevis is a flower longhorn beetle in the subfamily Lepturinae of the family Cerambycidae. The species is characterized by abbreviated elytra relative to other members of the genus, a trait referenced in its specific epithet "brevis" (short). It belongs to a group of diurnal cerambycids that visit flowers as adults. The species has been documented in North America, with records from Canada and the United States including Vermont.
Labidomera clivicollis
Swamp Milkweed Leaf Beetle, Milkweed Leaf Beetle
Labidomera clivicollis is a large leaf beetle specialized on milkweeds (Asclepias spp.). Adults and larvae feed on milkweed foliage, sequestering cardiac glycosides for chemical defense. The species exhibits aposematic orange and black coloration as part of a Müllerian mimicry complex with monarch butterflies and other milkweed feeders. Reproduction is photoperiodically controlled, with short day lengths inducing adult diapause. Larvae suffer high predation mortality, particularly from ground-dispersing predators.
Laccophilus biguttatus
Laccophilus biguttatus is a small predaceous diving beetle in the family Dytiscidae, first described by William Kirby in 1837. The species has a notably wide distribution spanning both the Nearctic and Palearctic regions, making it one of the more geographically extensive members of its genus. Like other Laccophilus species, it inhabits freshwater aquatic environments where it functions as an active predator.
Neohaemonia nigricornis
Neohaemonia nigricornis is an aquatic leaf beetle in the family Chrysomelidae, subfamily Donaciinae. The species inhabits freshwater environments in North America, with a distribution spanning the northern United States and southern Canada. As a member of the tribe Haemoniini, it shares adaptations for aquatic life with related genera, though specific biological details remain poorly documented in published literature.
