Vesperus bolivari, a very rare species occuring in South of the Iberian Peninsula (Portugal, Spain), has been described by Manuel Paulino de Oliveira in 1890 [▽].
The biology of the species is similar to other species of the genus, id est larvae develop on the roots of deciduous trees and shrubs.
The adults emerge in August-September and are active at dusk / early night hours until November-December (Algarve Coast). Males fly on warm windless nights and can be attracted
by the ultraviolet light. Females are very rarely collected due to the hidden way of life, during the day they are hidden under stones and plant remains and because they are apterous,
unlike males, they cannot be attracted to the light [▽].
|Body length:||♂♂ 17-25 mm / ♀♀ 21 - 28 mm|
|Life cycle:||2 and more years [?]|
|Adults in:||August - December|
|Host plant:||polyphagous on the roots of decidous trees and shrubs (Vitis, Olea)|
The depicted male beetle was collected in Lagos environs (Faro district, Algarve region, Portugal) on September 61, 2022.
Collected by our friend Marcos López, to whom we gratefully thank for the depicted donated specimen.
