'nanny jewel bug'), also known as the flat-headed wood-borer, is a metallic, bullet-shaped, woodboring beetle of the Buprestidae family.

This species is present from May through August and is attracted to sun, preferring to fly during the hottest part of the day, feeding on young buds and tree leaves.

[1] The larvae are ideally adapted to woodboring, being dorsally flattened with a broad thorax.

Females lay approximately 75 eggs in the crevices of bark or on wounded trees and sometimes in the exposed beams of older houses where they become serious pests.

Occasionally males are selectively killed at the embryo stage by bacteria known as Wolbachia.
