Bluebottle feeding on the ivy... not sure if C. vomitoria or C. vicina.
No interactions present.
... that neither your nor my observation of a potential Calliphora attracted any attention, comment or even agreement.
I guess it depends on when the observation is uploaded and who is online around that time. I put a lovely fungus on a few weeks ago with no response either... http://www.ispot.org.uk/node/259698?nav=users_observations.
With flies confirming the ID is often very difficult. I've been trying to get the hang of it by joining the dipterists forum http://www.dipteristsforum.org.uk/ and diptera.info http://www.diptera.info/news.php both of which provide a forum for identifying flies, but even there you don't always get a response. Maybe worth raising this as a forum topic here...
You're right. I've been with iSpot for just over two years and can see quite a change now. Of course, there ARE many more people using iSpot, which is great, but it is getting to be what seems like a matter of luck with id help, especially from "experts".
