Clitostethus arcuatus
Horseshoe Ladybird
Clitostethus arcuatus is a minute ladybird beetle in the subfamily Scymninae, measuring 1.3–1.5 mm as an adult. Native to Europe, it has been introduced or reported from Bermuda and is expanding its range northward in European Russia. It serves as an important biological control agent of whitefly pests, particularly the ash whitefly Siphoninus phillyreae, and has been evaluated for augmentation biocontrol programs.
