Tetrops

Tetrops

*Tetrops* Kirby, 1826 comprises small, robust longhorn beetles of 4–9 mm, clad in sparse fine dark pubescence and typically black with pale elytral apices — a livery that renders them remarkably cryptic on the bark of their hosts. The genus is associated exclusively with Rosaceae, developing in the thinnest weakened or dying twigs of fruit trees and shrubs such as *Prunus*, *Malus*, *Pyrus*, and *Crataegus*, making it a minor but recurring nuisance in orchards and avenue plantings. Larvae mine subcortically before entering the sapwood to pupate; development is completed in a single year, with adults appearing from April to June on dying branches and leaves, most active in sunny conditions.
