The "reticulata" form of "Sminthurinus aureus". "Original description on Flickr:" :"This chap is from my sister's garden the other day, a three photo stack. S. aureus f. reticulata is spreading across the country surprisingly quickly, from its first spotting a few years ago. This I think is the furthest north so far, in Yorkshire. I also found them to be pretty common in Manchester as I went up country."
