Minuscle Coenagriidae for ID
Los Angeles, Los Angeles County, California, USA
December 13, 1901
Size: about 25 mm lenght
This is the smallest damsel that I've seen ever. Pinned specimen exhibited at Harvard Museum of Natural Sciences. Please help ID! Thanks!

Can't make out the colors,sorry
It might be an immature female Ischnura verticalis. Check there and see what you think. Also, the date here looks different from the date on the label. You can click on Edit and fix that, unless 1897 doesn't work on BugGuide??

Hmmm. Now I see. I've put the date correctly. It's BugGuide system who apparently doesn't accept dates prior to 13th December 1901 (it's strange that also the day and month changed, as I've put 29th July 1897, that is the date writen in the label).

 
Computer limit
A common date format used internally in computer systems covers the range December 13 1901 to January 18 2038, and no more. (Technical details: a signed 32 bit count of seconds relative to January 1, 1970, which was a date in the recent past when the format was invented. They wanted a simple way to represent times relevant to the computer system they were using. 2038 was far beyond the lifetime of the computers the software ran on, but the software outlived the hardware.)

 
Oh, blame! I must have been m
Oh, blame! I must have been mixed two label photos :( I've put the data of the label that I believed to belong to this individual, but must be another!
It's smaller than an Ischnura. Maybe a dwarf individual by poor nymphal development? Anyway, if it's I. verticalis I don't need this photo - I have better ones of alive individuals :D So feel free for frass or delete the image :)

Thanks a lot by your reply! :)
