I went mid-range, β±5.6 at 1/250 sec.
Those blossoms open up right after dark, the bees and wasps swarm 'em. I may try and get some flash shots later, and try not to get stung! Those wasps are in-ground yellow-jackets, really aggressive if they get PO'd. The guy doing our pest control was due to be here early yesterday but came down with a (the?) flu, so we wait 'til he's well again to rid the nest... Mits was bitten twice, me once, before we'd realized they were around!
