A fly 6-8mm long photographed on a nettle leaf. I wish I knew enough to identify these even to genus level. Can anyone help, please?
No interactions present.
Like you, I'd really like a way to get these things id'd, but alas there is no shortcut. If pushed, I would say this one is probably Muscidae, based on the venation (long veins not bent forward), but I could easily be wrong. No good field guide, many can only be split by the old microscope/scalpel trick and much scope for error. However, persistence can pay off and there are some really helpful guys on here. I would start by trying to get much better photos than this, and from several angles - the legs, antennae and abdomen markings are often important. There are some easier families where you can start, like the blowflies for example. Muscidae probably not the easiest.
I think it is more likely to be Anthomyiidae, which are even more difficult than Muscidae.
I don't think this is Helina impuncta (i not e) or even a muscid, and in any case Helina can't be identified to species from pictures like this.
