Freeing the Pond Olive Mayfly

Once again the brown wheelie bin for garden waste came up trumps with a new species for the backyard - this time my first mayfly, a Pond Olive (#301) with its lovely long tail streamers.  Mayflies are usually found by ponds and streams, so God knows how it got in my compost bin, as I'd only been pulling up some potato plants and a few weeds; certainly nothing from any pond.  Apparently it's a myth that mayflies only live for a day - even so, spending a large proportion of your life shut in a dark wheelie bin is a bit tragic.  I was happy to liberate it.
