Orchestes rusci
This record describes Orchestes rusci (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
A tiny weevil of just over 2 mm in length. The larva mines Birch leaves, creating a broad gallery leading eventually to a hole in the leaf where the larva has cut out a circular leaf sandwich. This falls to the ground with the larva inside, and it pupates in leaf litter. The only other leaf miner on birch that creates holes in Birch leaves is the moth Heliozela hammoniella . Other Orchestes mine leaves of differnt tree species Adult: Unless identified by a recognised expert, photographic evidence of the adult 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. If the mine is recorded, provide a backlit photograph showing the gallery and leaf excision or larva in the mine. Peak time to search for adults is from May to September. Larvae mine the leaves of Birch from late Spring. Widespread and fairly frequent in Britain. http://www.leafmines.co.uk/html/Coleoptera/o.rusci.htm https://bladmineerders.nl/parasites/animalia/arthropoda/insecta/coleoptera/polyphaga/cucujiformia/curculionoidea/curculionidae/curculioninae/rhamphinini/orchestes/orchestes-rusci/

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Orchestes rusci. 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.
