The
hoverflies are true flies ( Order Diptera ) in having just
two wings
and a pair of club-shaped organs known as
halteres which aid flight. They can be seen almost anywhere
there are flowers where they feed on nectar and pollen. Most
common species, about 40 in number, appear in July to August.
The larvae, commonly known as "Rat-tailed Maggots" live
in a variety of habitats including drains, sewage, streams & ponds.
The Bee Fly is also a true fly and is so-called because of
its furry body (i.e. a bee mimic). Common at flowers in early
spring when its long proboscis is used to suck nectar. It
is harmless in having no sting in spite of its appearance.
Its larvae attack grubs of solitary bees and wasps in their
underground nests. There are several species in Europe. |
