Explanation of Names
Ptinus variegatus Rossi 1794
Size
3-4 mm
Identification
Elytra with two wavy white bands, the anterior one usually extending to shoulder and along side margin. Pronotum with projecting latero-dorsal humps and rather short pubescence, pale, denser and scaly in middle. Not conspicuously dimorphic.
Range
adventive to e. US, Calif. - Map (BG data)(1)(2), native across s. Europe (sw France to se Ukraine)
Habitat
Data scarce; habits described as similar to that of P. sexpunctatus (larvae scavenge in nests of solitary bees)
Remarks
Apparently no published NA records. With existing keys, it will key out as Ptinus bimaculatus, but is easily separated from the latter by shorter pronotal pubescence, adpressed and scaly in middle.
