Two Wings

Halteres beat rapidly and help the insect sense rotation during flight.

Hoverflies

Many mimic bees or wasps but do not sting.

Decomposers

This helps recycle nutrients.

Predatory Flies

Some larvae also prey on pests.

Mosquitoes

Only females of many species take blood meals, which provide nutrients for egg production.

Disease Ecology

Disease risk depends on mosquito species, pathogen, climate, human behavior, and public-health control.

Mimicry

The resemblance may discourage predators.

Ecological Importance

They pollinate plants, recycle waste, feed wildlife, and support scientific research.
