red admiral

The first one I've seen this year and I saw it as I walked around Langsett Reservoir. There were lots of butterflies out but not many species - ringlet, gatekeeper, meadow brown and this one... 

The extras are of a huge fly/hoverfly that I haven't ever seen before and I have no idea what it is despite doing a lot of searching. The best I came up wth was - Cynomya mortuorum, a male. But the photos I found only 'sort of look like this one. The 2nd extra is of it + a soldier beetle so you can see how large it was...
