Last night's dragonfly action

At midnight last night I went into the garden to cool down and found this dragonfly in the process of emerging. The photos aren't brilliant because of flash, but at least I got the main stages. I'd love to have stuck around and seen what colour it became, and also to check it managed to fly away unscathed. But this morning the exuvia's empty, and there's no sign, so who knows? We're aware of about ten dragonflies hatching this year, but I bet we've missed some. Not bad for a small garden pond.
