Species description

Species description

This hoverfly is one of the sub-family Platycheirus, Platycheirus scutatus. It is found throughout the northern hemisphere. Its larvae feed on aphids. It has a long flight period in the UK, preferring grassland, scrub, woodland and gardens.

This is a small hoverfly. From wing tip to wing tip, it measures between 5 and 7.5 millimetres. Its body length is no more than 5 millimetres.

Species family information

True to their name, the hoverflies hover around flowers, and then alight to feed on nectar and pollen. They are very important pollinators, and despite the fact that some look like wasps or bees, this is just mimicry and helps to keep potential predators at bay. Hoverflies have no sting, and have short, drooping antennae. The larvae are as useful as the adults, in that they feed on aphids. We have a photograph-filled blog post about all the hoverflies that we have seen in the Cemetery that may be worth your time.

Category information

Insects evolved in the Ordovician from a crustacean ancestral lineage as terrestrial invertebrates with six legs (the Hexapoda). This was the time when terrestrial plants first appeared. In the Devonian some insects developed wings and flight, the first animals to do so. An early flying group was the Odonata from the Carboniferous, the damselflies and dragonflies, which have densely-veined wings and long, ten-segmented bodies. They are day-flying carnivores, with an aquatic larval stage, so are commonly seen flying near water. The carnivorous larvae are called nymphs. Odonata species are short-lived, damselflies surviving for 2-4 weeks, dragonflies for up to 2 months.

Some insect groups in the Cretaceous co-evolved with the flowering plants, and they have had a close association ever since. These groups are the Hymenoptera (bees, wasps, and ants), the Lepidoptera (butterflies and moths), the Diptera (flies), and the Coleoptera (beetles). The diversity of beetles is astonishing. Of all the known animal species on the planet, one in five is a beetle!
