Insects - friend or foe

Whilst mowing the lawn in the hot sun today (at last), lots of flying insects lifted up around the mower as I worked. They looked like something out of a swamp (sort of giant gnat).

Must admit I don't know what they are for sure but the question is are they a gardeners friend or foe, in other words of course, will they eat aphids?

Perhaps just give me a nasty bite! :(

P.S. What makes you think I live in a town? :D :D

 

As far as I'm concerned, definitely foe!! They always bite me too! I don't care if they eat aphids, they eat me, and I don't like it! Seriously though, I don't know if they're helpful - must look it up!

 

It doesn't exactly ansewr the question - but it's interesting anyway - have a look here...http://www.wisegeek.com/what-is-the...ndflyingants_ad=027341&_search_kw=flying ants

 

Gnats, mozzies and midges only eat BLOOD!

 

Thanks for reply everybody, I take it as a foe then! Hope not to see them very often! :( :(

Thanks again
