Cerambycidae (Unusual Elytra)

The typical Cerambycid is a beetle with long antennae, slightly enlarged femurs, and long elytra. In the case of this Cerambycid, the elytra have been reduced to nub-like coverings on the thorax, with the wings almost completely exposed. I have another entry about a Cerambycid of the subfamily Lepturinae, or flower longhorns. The common characteristic they share is the general trend of the elytra narrowing near the end of the abdomen, creating a shouldered look. When I first saw these insects, I almost mistook them for wasps, since they did not have easily visible elytra. There were quite a few darting among the flowers in Carmel.

Coleoptera; Polyphaga; Chrysomeloidea; Cerambycidae; Lepturinae; Necydalini; Necydalis laevicollis
Common Name: Flower Longhorn (Lepturinae)

The tribe Necydalini comprises of longhorn beetles with very short elytra that expose the abdomen and long flat wings with three veins in the post-cubital region. There is some debate whether they belong in Lepturinae or Molorchinae; however, it is generally agreed that the larvae, wing venation, and adult mouthparts most resemble those in the subfamily Lepturinae.
