I took these photo's in the south Derbyshire countryside last week and have been trying to identify the insect. I've looked through NHM's Bee identification pages and can't see anything similar. Is it a bee, a wasp, a fly? Any help would be much appreciated. I like to know what I'm looking at when taking photo's of wildlife and nature. Thanks a lot.
From what I can see I would say that this is a species of Eristalishoverfly (Diptera: Syrphidae) several species of which are honeybee mimics. Eristalis tenax (aka the Drone Fly) is one of the more common species and all over flowers at the moment.
