Wow!
Cool shots!

She has the look of an aphid, I think, and they are known to do this. See guide page. However, the parthenogenetic females (the ones that have live birth) are usually supposed to be wingless.

 
It's kind of big for an aphid
It's kind of big for an aphid isn't it ?

 
Yes, but
check out this one:



Unfortunately there's no measurement on Lynette's image but the colors match yours and the name (Giant Bark Aphid) suggests it is a big one. I'm assuming your measurement includes the wings?

 
So what about the live birth
So what about the live birth and wingless issue ?

 
:)
The method of birthing (ovoviviparity) is constant. Parthenogenesis only relates to how the egg is fertilized.

 
Thanks, Joe
so the difference is, the ones that are fertilized can be either male or female, and the ones that are not are female clones of the mother?

 
So is the Giant Bark Aphid a
So is the Giant Bark Aphid a definite ID ?

 
I would say so.
There is a nice fact sheet on this insect somewhere on the 'net, like from TAMU (Texas A & M).

 
There's an article linked on the info page
which says the females of this species that lay eggs are wingless, so this live birth from a winged female makes sense, contrary to my comment above.

Nice to be able to get an aphid to species - it happens so rarely!
