Pollenia amentaria agg.

    Alt Name
    Pollenia vespillo

    The clusterfly Pollenia amentaria can be recognised because the black tergites lack obvious dusting – however there are similar species and detailed examination would be required for a certain identification. For this reason we have decided to treat the species as an aggregate. Fresh specimens of Pollenia amentaria with lots of golden hairs on the thorax are very striking. Males have a broad build and eyes that are only narrowly separated. A sharp and narrow facial keel is present between the antennae. This is also the only clusterfly with 5 to 6 pairs of strong scutellar marginal bristles (other species have 3 to 4 pairs). Females are also unusual in having an anterior preapical bristle on the mid femora.

    Identification difficulty

    It can occur in a wide range of habitats.

    When to see it

    Life History

    The larvae are thought to attack earthworms like other Pollenia species.
