[1] In its native range in China, it causes significant damage to its single host, Ailanthus altissima, tree of heaven.

Eucryptorrhynchus brandti produces one generation per year, with larvae and adults overwintering.

Adult weevils feed on leaves, buds, and petioles.

Larvae develop under the bark of the host plant, boring and feeding, to emerge as adults through round emergence holes 4 millimeters in diameter.
