Saperda populnea, the small poplar borer,[1] is a species of beetle in the family Cerambycidae which forms woody galls on twigs of poplars and willows. It was described by Carl Linnaeus in 1758.[2]
Description
It is a medium-sized (9–15 mm), slender, dark longhorn beetle.The body is cylindrical with dark, protruding hairs. The antennae are shorter than the body, each segment two-toned with a grayish inner part and a black outer part. The head has a grey-yellow marking on the forehead shaped like an upside-down V. The pronotum is rectangular from above, slightly wider than long, with grey-yellow stripes on the sides. The elytra are parallel-sided, only slightly wider than the pronotum, grey-yellow, densely covered with dark spots except for some areas left as light spots, usually four on each wing. The legs are grey-brown.[3]It resembles Agapanthia villosoviridescens but is much more robust and also lives in a different habitat. The beetles can be found from May to July, when the female makes a horseshoe shaped cut and laying an egg in the incision.[4] The gall develops in an internode as a symmetrical swelling, which can be 20 mm long, and contains a yellowish larva or pupa in a single elongate chamber. An exit hole is made in the spring.[5] It is most common on aspen (Populus tremula) and also found on black cottonwood (P. trichocarpa), black poplar (P. nigra) and goat willow (Salix caprea).[6] In Britain the gall is commonest on the young twigs of aspen.[5]
