Diet

• Adults: Adults are associated primarily with woody vegetation, although their exact feeding habits are poorly documented.

• Larvae: Most Thryallis species are believed to develop in dead or recently dead branches and trunks, where the larvae tunnel through the wood.

Range

• Thryallis is a genus of longhorn beetles (Cerambycidae) in the subfamily Lamiinae, tribe Anisocerini. Seven species are currently recognised in the genus.

• The genus ranges from southern Texas through Mexico and Central America to Costa Rica.

• It is occasionally sighted in Zihua. The genus is represented in the broader Guerrero fauna, and the tropical dry forest around Zihua provides appropriate habitat.

Habitat

• Primarily associated with tropical dry forest, tropical deciduous forest, woodland and areas containing dead or recently dead trees.

• Adults may be found resting on branches, trunks and foliage, where their mottled appearance can provide excellent camouflage.

• Around Zihua, examine dead branches and standing dead trees, particularly during the warmer and wetter months.

• Some species have also been collected by beating vegetation or at lights. T. sallaei, for example, has been recorded on recently dead trees.

Size

• Adult length: approximately 10–25 mm (0.4–1.0 in), depending on species.

• Body generally elongated and robust, with the long antennae characteristic of longhorn beetles.

• Colouration is commonly brown, grey, tan or mottled, often providing camouflage against bark.
