Habitat

This species inhabit deciduous forests, especially beech forests and hedge rows.[3]

Description
Side view

Dinoptera collaris can reach a length of 6–9 millimetres (0.24–0.35 in).[3] Elytra are bluish-blackish and rather hairy, with dense puncture. Pronotum is almost spherical, usually orange-red, sometimes dark, with sparse punctuation. Antennae are quite long. The abdomen is orange-red.[4][5]

This species is rather similar to Acmaeops marginatus, Acmaeops pratensis and Acmaeops septentrionis.

Biology

The life cycle lasts two years. The larvae develop under the loose bark, especially of oaks, aspens or apple trees. They are polyphagous wood borers in deciduous trees (Quercus, Pyrus, Acer, Fraxinus, Populus, Malus, Cornus etc.) [4][3] They overwinter and pupate the following spring.[5]

The adult beetles can be found from April to August feeding on pollen of valerians (Valeriana species), common hawthorn (Crataegus monogyna), elderberry (Sambucus species), sweet chestnut (Castanea sativa) and European pear (Pyrus communis).[1][6]

gollark: The entry-level desk job things will probably get increasingly automated away anyway.
gollark: I didn't say that that produces *good* outcomes for people involved.
gollark: Apparently the (or at least a) reason for this problem is that a degree works as a proxy for some minimum standard at stuff like being able to consistently do sometimes-boring things for 4 years, remember information and do things with it, and manage to go to class on time. So it's useful information regardless of whether the employer actually needs your specialized knowledge at all (in many cases, they apparently do not). And they're increasingly common, so *not* having one is an increasing red flag - you may have some sort of objection to the requirement for them, but that can't be distinguished from you just not being able to get one.
gollark: The solution, clearly, is to ban asking people if they have degrees when hiring, and force them to be tested on other things instead.
gollark: That wouldn't destroy it.
