Growing collection

It is such fun searching for more Hoverfly species to add to my collection. Then coming home and looking in the books and the Internet for an i.d.
This one I believe to be Eupeodes corollae. The photo also has a little fly which I have not been able to identify.
This is a migratory species. What a long way to fly for such a tiny creature.

A P.S. on yesterday's Trig Point. The one on Arnside Knott was built in 1949 and cost £10-14s-6d.
