Size 2.1 to 2.8 mm. Body black with a distinct metallic green lustre antennae and legs are mostly pale orange-yellow. The rostrum is long and curved; in the female as long as the head and pronotum combined and entirely dark metallic, in the male as long as the pronotum and pale orange in the apical half or two-thirds.

Unless identified by a recognised expert, photographic evidence is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used. Note the beetle's size and describe the identifying characters. Also note the host plant you found the specimen on. It is advisable to retain the specimen in case further checks are needed.

Found on Mallows growing on waste ground or roadside verges etc.

Late April to August.

In the UK it is locally frequent in England north to Nottingham and mostly coastal in the West Country and Wales. It appears to be absent from Scotland.

Not well recorded in Leicestershire and Rutland, but targeted recording effort focusing on Mallow may show it to be more common than records indicate.
