Dot Ladybird
Stethorus pusillus is the smallest European ladybird beetle, belonging to the family Coccinellidae and subfamily Scymninae. This species has been documented as a host for the ectoparasitic fungus Hesperomyces coccinelloides, with the first Polish records representing the northernmost and easternmost occurrence of this fungus. The species has been collected from roadside willow trees and floodplain forests in Poland, and is known from various European localities including Spain and Belgium, as well as from the Azores islands.
