Urocerus taxodii
Taxodium horntail
Urocerus taxodii is a species of woodwasp in the family Siricidae, described by Ashmead in 1904. As a member of the genus Urocerus, it shares the characteristic elongated, cylindrical body form and prominent cornus (horn-like projection at the abdomen tip) typical of horntails. The species is associated with Taxodium (cypress/bald cypress) as a larval host, as indicated by its specific epithet. Like other siricids, females possess a long ovipositor for drilling into wood to deposit eggs, and they vector wood-decaying fungi that serve as food for their larvae.
