Loosestrife Weevil - Nanophyes marmoratus

for well-marked specimens

It may be possible to identify this species from the elytral markings if they are clear, otherwise, 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. It is advisable to retain the specimen in case further checks are needed.
