Apion frumentarium (Linnaeus, 1758)

Female
Common across England, Wales and southern Scotland on the leaves of larger Docks; Curled (Rumex crispis) , Great Water (R. hydrolapathum), Sharp (R. conglomestus) and Broad Leaved (R. obtusifolius). Adults are active during warm weather on the underside of leaves from early April until early June, although we have very occasionally found single examples under debris near Croxley Common moor during the winter. Where the foodplant is common the weevils may be present on every plant but quite often only a few are attacked. When the temperature drops they move deep down in between the bases of leaves and so can be difficult to find without damaging the plant. Larvae feed within the stem or rootstocks.

2.5-4.5mm. Distinguished from other red Apion spp. by the head structure; completely punctate, including the underside, between eyes and prothorax side margin, this punctuation being similar to that on pronotum. Head long, with temples subparallel and at least one and a half times longer than the eye when viewed from above (A. cruentatum). Eyes and claws black otherwise completely red/orange and clothed with sparse creamy white pubescence.
Male rostrum broadest subapically and shining in apical half, in female broadest at antennal insertion and with apical half more shining.
