Identification
Mesonotum divided by nearly straight, transverse groove between bases of fore wings, the groove separating from the mesoscutum a triangular area (axilla) on either side of scutellum. Antennae inserted above above level of ventral margin of eye. Head without a crown of teeth. Abdominal tergum 1 divided medially. Abdominal terga angled outwardly. Similar to horntails but with no horn at the tip of the abdomen above the ovipositor.
Food
The larvae bore in the dead or decaying wood of deciduous trees, particularly small branches(2)
Remarks
Not considered to be of economic importance as larvae neither attack living branches nor are they known to attack structural wood in homes. They may be seen indoors due to being brought in with firewood.(2)
