| Re: Ground Nesting Flies
No, I don't think they carrion flies of any kind. They have a bluish shimmer to them when they're flying, but if you can catch them still enough, there's no blue on them. Also they don't have red eyes as far as I can tell.
Iwondered whether they might be groundnesting bees, but they don't look like bees at all. Also wopndered whether they're a kind of plant root fly, which causes problems in the vegetable plots. However, my Observer's Book of Insects shows nothing that I can recognise. Index isn't helpful either if one tries to look for things like ground-0dwelling or ground-nesting...
Tried 'googling 'ground nesting flies as well, to no avail. |
