Long-horned Bees (Genus Melissodes) are active from July through September, with at least 9 species known from Vermont. A few are true specialists, while others have a general preference for composites, and at least one species is a broad generalist. Field identification of most species is hard or impossible, thought there are a few distinctive ones. Host to Longhorn-Cuckoo Bees (Triepeolus).

Long-horned Bees are medium-large bees that can be abundant in some context. Females have very long scopal hairs on their hind tibia and males have absurdly long antenna (hence the common name).
