Apion rubens
This record describes Apion rubens (species). Recorded family: Apionidae. Recorded order: Coleoptera.
Identification and Appearance
Apion rubens is a small (2 to 3 mm) reddish coloured weevil. The larvae mine the leaves of Sheep's Sorrel (Rumex acetosella ) causing galls to form as swellings along the mid rib or petiole. These are often reddish or sometimes yellow in colour. (see further information below). 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. Larvae mine the leaves of Sheeps Sorrel. The revised British Plant Galls Keys indicates that these galls are not well known and identification using the keys should be verified by rearing and identifying the adults.This is rarely done, so although we have found no other likely causer for the galls illustrated, we wish to point out that they have not been proven by rearing through to the adult stage.

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Apion rubens. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
