Miniature Blue-Winged Olives
This common name refers to only one genus.
These are often called Miniature Blue-Winged Olives.
The only Acentrella
species commonly reported to be important to anglers is Acentrella turbida
, though Acentrella insignificans
is important in some western locales. See the species pages for distribution and timing details. This genus is one of two (including Heterocloeon
) that can easily be distinguished from other Baetidae
genera by the presence of a conical mesonotal projection (Conical mesonotal projection: small cone shaped spike sticking up from the top and front part of the middle thorax segment.)
. A. turbida
lacks hindwings which is useful for distinguishing this species from all others in either genera. A. turbida
was previously known by the names of its synonyms (Synonym: A former name of a taxon, usually a species. Entomologists frequently discover that two insects originally described as different species are one in the same, and they drop one of the names. The dropped name is said to be a synonym of the remaining name. These changes take a while to trickle into the common knowledge of anglers; for example, Baetis vagans is now a synonym of Baetis tricaudatus.) Pseudocloeon turbidum
in the West and Pseudocloeon carolina
in the East.
