Stenocorus validicornis validicornis, a nominotypic subspecies occuring in Kyrgyzstan and Uzbekistan, has been firstly mentioned as Toxotus validicornis by Maurice Pic in 1900 [▽] and eventually described in detail by the same author in 1906 [✧]. Information on the larval biology of the species/subspecies are insufficient, but the mass collection of beetles in mountain meadows in the absence of trees and shrubs suggests a connection between the larvae and the roots of herbaceous plants. It is assumed that the population of Sary-Chelek lake environs (Kyrgyzstan) is related to the Ferula. Adults, active from June to August, are diurnal and anthophilous (can be found mostly on Ferula) [❖].

Body length:♂♂ 14 - 24 mm / ♀♀ 16 - 30 mm
Life cycle:unknown
Adults in:June - August
Host plant:probably in roots of herbaceous plants [?? Ferula spp., Apiaceae]
Distribution:Kyrgyzstan, Uzbekistan

The depicted beetle was collected in Sary-Chelek Lake environs (1860 m a.s.l, Sary-Chelek Nature Reserve, Jalal-Abad province, West Kyrgyzstan) on July 11, 2016.
