Syritta

Syritta is a genus of hoverflies (family Syrphidae). These small, often metallic-looking flies are found primarily in the Holarctic region. Characterized by their distinctive club-shaped hind femora, Syritta species are commonly observed visiting flowers, where they feed on nectar and pollen.

Morphology:

Syritta hoverflies are typically small in size, ranging from approximately 5 to 8 millimeters in length. The key distinguishing feature of this genus is the significantly enlarged, club-shaped hind femora, which are thicker towards the distal end. The coloration of Syritta species varies, but often includes metallic hues of bronze, green, or blue. The abdomen is usually marked with patterns of yellow or orange.

Ecology and Behavior:

Adult Syritta hoverflies are active flower visitors, playing a role in pollination. They feed on nectar and pollen, obtaining essential nutrients for their survival and reproduction. The larvae of Syritta species are typically found in decaying organic matter, such as compost heaps, dung, and rotting vegetation. They are saprophagous, feeding on the decomposing material.

Distribution:

Syritta hoverflies are distributed across the Holarctic region, which encompasses North America and Eurasia. They are commonly found in a variety of habitats, including meadows, gardens, and woodlands.

Taxonomy:

Syritta is a well-established genus within the family Syrphidae. The classification of individual species within the genus has been subject to revisions, but several species are widely recognized.

Relationship to Humans:

Syritta hoverflies are generally considered beneficial insects due to their role in pollination. Their larvae also contribute to the decomposition of organic matter, playing a role in nutrient cycling. They are not typically considered pests.
