Thanks Atul. it's amazing !!, All the changes that occur with the change in a season!. Fall has brought in so much more. unfortunately I am nursing a sore foot after all my summer hiking on top of Mt Diablo. Things are at a standstill :) In the mean time I might as well fine tune my work. Do my write ups , Id's etc etc. Long way to go in terms of photography. But am really enjoying the awesome spottings coming in on Project Noah.Nice to hear from U!!
Atul

@misako.hill i think it is Enallagma ebrium but not sure that site did not name this one. @Emma yes i discovered that when researching dragonflies a few months ago there are even some that have virtually the same phenotype genetics is used to mainly distinguish between them
misako
It is simply amazing! :)
HemaShah
Besides Lady bugs and Cotton tails of course!
HemaShah
Did you know that there are more than one species of Sparrows,squirrels ,Scrub jays , bluets .... Some of the surprises i recently discovered!
misako
wow--and I thought ladybug species were hard to ID! I have an Enallagma that looks exactly like this photo: http://www.dragonfly-site.com/pictures-28.html that @ hg_williams. It has the little black dot on the segments. What is the species name of that one?
HemaShah
@hg http://www.odolep.com/d_coenagrionidae/damsel_males/damsel_males.htm The differences are very subtle.
hg_williams3
you saw it i real life so you might pick up a few some-what cognative differences that i cannot
hg_williams3
That may very well be it but also compare these http://www.pugetsound.edu/files/resources/4295_Enabas+Enaasp.jpg male and pair Enallagma basidens and male Enallagma aspersum
HemaShah
@ hg_williams, I think it is "Enallagma annexum" http://fwp.mt.gov/mtoutdoors/HTML/articles/portraits/damselfly.htm Northern Bluet Damselfly The color of the legs is not exactly white but it is not black either. Waiting for your feedback. Thnx
