This little in Central Europe a very common Cerambycid develops in a variety of broadleaf trees and shrubs (especially in Rosaceae - Malus, Pyrus, Rosa, Crataegus, Prunus etc.). Larval development in the thinnest weakened or dying twigs of the host trees. The larvae feed subcortically and pupate in a pupal cell in the sapwood, or even in its shallow depression. It overwinters in the larval stage. Adults occur in May and June on dying twigs, leaves and in sunny weather also on various blossoming trees and shrubs (e.g. Crataegus, Malus, Prunus) [✧]

Tetrops praeustus species cluster comprises several very similar species and subspecies (T. praeustus praeustus (Linnaeus, 1758); T. gilvipes (Faldermann, 1837); T. praetermitus Sláma, 2020 [❖]; T. peterkai Skořepa, 2020 [▽]) that are thanks to similar bionomy and overal look often confused or misidentified. Valuable information on the taxonomy of Central European Tetrops praeusta-cluster can be found in the works of Polish (Jacek Kurzawa, Marek Miłkowski, and Jerzy M. Gutowski, 2020) and German colleagues (Ralf W. Hass and Andreas Pütz, 2022)[✮][✳].

According to the authors of the website, the entire cluster of these taxa, in which the diversity of habits of adults is also influenced geographically, needs a comprehensive revision using not only classical morphology in larvae and adults but also DNA analysis.

Body length:3 - 6 mm

The depicted mounted specimens were collected in : A - Řeháč (Jaroslav village environs, Pardubice district, Pardubice region, East Bohemia, Czechia) on April 30, 2005; B - Umag environs (100 m a.s.l., Istria county, Croatia) on May 8, 2012. The living beetle was photographed in Králův Dvůr - Záhořany (Beroun district, Central Bohemia, Czechia) on May 8, 2019.
