Clover Seed Weevil

Protapion apricans, one of the weevils sharing the common name clover seed weevil, is a small apionid weevil in the family Brentidae (subfamily Apioninae), order Coleoptera. Unlike Tychius picirostris, which belongs to Curculionidae, Protapion species are classified within Brentidae, reflecting different evolutionary origins despite a broadly similar ecological role. P. apricans is a specialized herbivore of red clover (Trifolium pratense), with larvae feeding within developing flower heads and seeds rather than directly ovipositing into seed pods as Tychius does. Adults feed on the leaves and stems of clover before mating, and females insert eggs into developing flower heads where larvae feed on immature seeds and florets. P. apricans is considered an important pest of red clover seed production in Europe, capable of causing significant yield losses in clover seed crops. The species is distributed across Europe and has been documented from Norway and Sweden. It inhabits meadows, agricultural fields, and grassland habitats wherever red clover grows. P. apricans is classified as Least Concern on the IUCN Red List, reflecting its widespread distribution and stable populations throughout its European range. The species can be distinguished from closely related Protapion species by morphological characters of the rostrum, pronotum, and elytral punctation, requiring careful examination for accurate identification.
