Leiopus linnei, described by Henrik Wallin, Ulf Nylander and Torstein Kvamme in 2009 [❖], is in Europe sibling species to well known and highly variable Leiopus nebulosus (Linnaeus, 1758). Both species differ in combination of characters, including the male genitalia and female spermathecae. Leiopus linnei appears to be common in central Europe and is here also probably more anbundant then L. nebulosus, which is predominantly recorded from coastal areas of Europe. The biology of the species is the same as that of the L. nebulosus [❄].

L. linnei and L. nebulosus are very similar morphologically and their identification is difficult and possible only by experienced taxonomists. For this reason, a supporting determination method these two species based on hind wings measurements was developed and published by Robert Rossa, Jakub Goczał and Adam Tofilski in 2017 [✧].

Body length: ♂♂ 5.0–9.2 mm / ♀♀ 6.4–9.5 mm
Life cycle:1 - 2 years
Adults in:May - July
Host plant:polyphagous in deciduous trees (Fagus, Quercus, Carpinus, Juglans, Acer, Ulmus, Betula, Salix, Prunus)
Distribution:Austria, Bulgaria, Croatia, Czechia, Denmark, France, Great Britain, Germany, Macedonia, Norway, Poland, Romania, Slovakia, Slovenia, Switzerland, Ukraine

The depicted beetles were collected (DR - May 2, 2020) or reared (MP/ML - winter 2021) from larva found in a dead oak (Quercus sp.) in Křivoklátsko Protected Landscape Area (Central Bohemia, Czechia).
