Urban Invertebrates: Flies, Midges and Mosquitoes

Flies

They usually have a round body and large eyes. They are important pollinators, decomposers and food items for insectivores.

Ecological function: pollinator, decomposer, scavenger

Level in food chain: secondary consumer

Feeding behaviour: coprophagous, necrophagous

Microhabitat: near rotting material

Midges

They can be mistaken for mosquitoes, but they do not suck blood. Their hind legs are not larger than the front legs. Midges do not have a long needle like mouth-part. They are important pollinators.

Ecological function: pollinators, decomposer, 

Level in food chain: secondary consumer

Feeding behaviour: carnivore, detritivore, nectivore, coprophagous

Microhabitat: damp areas with a lot of shade

Mosquitoes

Their hind legs are larger than their front legs. Females will feed on blood when they need to lay eggs, but male mosquitoes do not suck blood and are useful pollinators. Mosquitos are important prey to many insectivores.

Ecological function: parasite, pollinator

Level in food chain: secondary consumer

Feeding behaviour:  nectivore, blood feeder

Microhabitat: damp areas with a lot of shade
