Curculionoidea

Weevils (6)

This final page separates the last two species that I'm currently able to feature, both of which are in smaller subfamilies that have not been previously covered.

The Hyperinae (cocoon weevils) subfamily includes 18 species, fourteen of which are in the Hypera genus and two each in Brachypera and Limobius. A general description for the two main genera Hypera and Brachypera confirms, square shoulders, rather straight-sided wing-cases, a thick rostrum with antennae inserted near the tip, and the importance of the shape of the scales on the wing-cases when trying to distinguish the species, particularly with Hypera. Of the two Brachypera species, only Brachypera zolius is widespread but, even so, not that common. It has a broader body and a short and very thick rostrum.

Molytinae includes 17 species in 11 genera that are separated into seven distinct tribes; a diverse group where most species are either scarce or rare and infrequently recorded, although some are locally common, but restricted by habitat. They are varied in morphology with few common features other than the head is small with large flattened eyes, a long robust rostrum and geniculate antennae with a long scape and distinct clubs. Having looked closely at the available distribution data, apart from the featured species below, I can only find two that could possibly be found locally; Hylobius abietis and Pissodes castaneus, both of which are associated with coniferous pine woodland. There are literally only a couple of records of each species from either Dorset (VC9) or South Hampshire (VC11), but they're two species that I'll be looking out for.

The Molytini tribe includes seven species in four genera that have been further divided into separate subtribes. The Molytina includes two Liparus species, which are our largest weevils. I believe that they are both 'nationally scarce'. The largest at 13-15mm is Liparus germanus which, as far as I'm aware, has only been recorded from a few sites in Kent. The species that I found Liparus coronatus, seen on two occasions at the same location, is a tad smaller and more widespread with scattered sightings across the south, albeit only with around 300 confirmed records.
