What it looks like: This 4-5mm long weevil is dark metallic blue, with a distinctly hairy surface. Its elytra have rows of punctures, and are shortened at the tip, exposing part of the abdomen. Its snout is relatively short, widening toward the mouth, and it bears a pair of short, weakly clubbed antennae.

Where you'll find it: Found throughout much of western North America, practically wherever oaks are found.

Natural History: Like most weevils, D. glastinus is a strict plant feeder, and is generally found on oaks, its favorite group of plants. The adults are active fairly early in the year. Attelabids generally are known as 'leaf-rolling weevils'. In this species the female lays her eggs within the leaf, often near the midrib, before severing leaf from the plant. The larvae mine through the dead and dying leaf tissue, eventually leaving the leaf to pupate in the soil.
