Cimberis attelaboides is a species of weevil from the family Nemonychidae and the superfamily Curculionoidea . A frequently used synonym in the older literature is Rhinomacer attelaboides .
features
The kind is 3 to 3.5 millimeters long and colored black or dark brown. Legs and antennae are red-brown, the tarsi darkened. The body is relatively densely covered with half-erect hairs that vary in color from white to yellow-brown on the top, but are always white on the underside. The body is elongated with wing-coverts on parallels that are wider than the pronotum. This is rounded on the sides and about as long as it is wide. The head and the eyes reach the width of the pronotum. The trunk is rather short, always shorter than the length of the pronotum, flattened towards the tip and a little wider. The antennas are turned in just before the middle of the trunk. They are long and slender with only indistinctly separated antennae lobes. The whole body is punctured, with the puncture of the pronotum being much weaker than that of the elytra.
Way of life
The species is bound to pines (genus Pinus ). The following host species are named: Scots pine , black pine , maritime pine , upright mountain pine , in Germany the species occurs only on Scots pine. The larva develops in the strobili, the male, cone-like "catkins" of the pine and feeds on the pollen grains, but also attacks the kitten's central axis. Eggs are laid on the still immature strobili as soon as they begin to open. At the end of the flowering period, the larva drops to the ground and finally pupates in the ground. However, it is not known which stage overwinters. Adult beetles are found from April to June.
Similar to the related species Doydirhynchus austriacus with a very similar way of life, Cimberis attelaboides is considered to be widespread, but is usually only rarely found.
distribution
The species has a significantly larger range than Doydirhynchus austriacus . It populates all of Europe and is spread across Siberia to the Russian Pacific coast. It is also found in northern Scandinavia and Great Britain. In Germany it is said to be more common in the north, but less common in the south than Doydirhynchus . In Baden-Württemberg it prefers the lower elevations, it was only found here in the low mountain range.
