According to Paul Whalley (
Butterfly Watching 1980)
Dave, they live up to 3 weeks. However, he also states Small Copper live about 3 weeks and I think you may have proved that to be an underestimate! Mind you I’m inclined to go with the Black Hairstreak given it’s narrow flight period.

Saturday 8th was mostly a drab, cool and cloudy affair, but there was a glimmer of hope that the clouds would break at some point in the afternoon. Given this, and the fact that Heath Fritillary are relatively easy to find when roosting, I hopped on to a train to Hockley. It was still cloudy when I arrived but walking along the bottom path, checking out any areas where lush growths of Cow-wheat was found it didn’t take much to find the first roosting one. A few snaps then looking round I noted a few more scattered around in ones and twos. More snaps and more looking produced more until I amassed around thirty sat quietly around me.
The merest hint of extra warmth by a slight thinning of the cloud had an almost immediate effect with wings creaking open all around me and I realised there were a few more than thirty!
The cloud thinned and thickened periodically with the Fritillaries reacting accordingly for the next hour or so until eventually it started to break up properly, and the usual Heath Fritillary shenanigans ensued. It would seem most of the females had already been mated as there was an endless procession of males harassing females as they fed, with in flight females routinely being followed a train of four or five eager males. I did come across one mating pair trying to remain unseen from the throng of activity.
In the end I didn’t move from this one small area for the twoish hours I was there, in total there were easily over a hundred here and every time the sun came out from behind a cloud they would rise en masse from where they’d sat out the cloudy spell, I always find this a most wonderfully ethereal experience.
Just to put David Lazarus's mind at ease, non of these images (or from the next post) were obtained by crushing of foodplants/roosting spots/anything else
