Neandra
pole borer
Neandra is a genus of longhorned beetles in the family Cerambycidae, subfamily Parandrinae. The genus contains at least two described species: Neandra brunnea and Neandra marginicollis. These beetles are atypical for cerambycids, possessing short, bead-like antennae rather than the elongated antennae characteristic of most longhorned beetles. They are known to bore in decaying wood and are attracted to lights at night.
Neandra brunnea
pole borer, longhorned beetle
Neandra brunnea, commonly known as the pole borer, is a species of longhorn beetle in the subfamily Parandrinae. It is unusual among cerambycids for its relatively short, bead-like antennae rather than the elongated antennae typical of the family. Adults range from 8–20 mm in length and are yellowish-brown to reddish-brown in coloration. The species is distributed across eastern North America, with adults active from March through November. Larvae bore into decaying wood, including wooden poles and posts in contact with moist soil.
Neandra marginicollis
Neandra marginicollis is a species of longhorned beetle in the family Cerambycidae, subfamily Parandrinae. It is one of two subspecies recognized within the species Neandra marginicollis, with the nominate subspecies N. marginicollis marginicollis described by Schaeffer in 1929 alongside the subspecies N. marginicollis punctillata. The species is found in North America. Members of this genus are unusual among cerambycids for their short, bead-like antennae and large, forward-projecting mandibles that give them a superficial resemblance to stag beetles.
