Oh, please do not be sorry for a wrong ID (esp. ob your own obs) otherwise I have to be all the time 
What is this spider here doing?
No really. It was injured, and what’s that green bubble near it’s leg?
Injured looks right, the droplests in a few places seem to be “blood-loss” (haemolymph) Which is quite an issue when you run on hydraulics.
I think it’s injured and bleeding.
Green blood?
What a feast!
If an invertebrate had red “blood” I would be much more confused. If you havent had a chance to learn about arthropod circulatory systems. Its worth having a look at the wiki of https://en.wikipedia.org/wiki/Hemolymph for an introduction on how it works.
On the other side of the hill (West Coast), I too have seen a surge of leptotarsus in webs. I need to look closer, but they are quite short bodied like Leptotarsus vulpinus, which seems to have a real surge in the past week.
On google it said they had blue blood, but you are right, it can be green too, after all, if the spider is so green, who expects the blood to be blue.
Once I was photographing an ambush bug eating a cerambycid beetle, when a Nursery Web Spider appeared out of nowhere and grabbed the beetle away and ate it! Got a series of photos of the event, here are a couple:

BTW, this little guy moved next to my window, so I decided to give him a name… any ideas?
Ralph (why? dunno).
Jeff the spider.
It’s a girly.. maybe Edda
This American Dewdrop (Argyrodes elevatus) that I posted in this topic earlier, is the first one spotted on iNat in Canada, so far. But since you introduced the metallics question, i thought I would give some details.
Last August, my visiting brother-in-law from Ottawa was keen on going with me on a bug crawl so I took him to one of my favourite local parks which is a large agricultural research facility on the shore of Lake Ontario.
While there, I just had to take him through this 100 ft long tunnel under a road that connects the center with a small woodlot. I had discovered that this tunnel was sufficiently long enough to provide shelter for many arthropods all year round, a huge safety port for my mid-winter no-bug blues.
We started walking in, and I started to point out some species as things got dimmer, and while waiting for me to adjust camera stuff, he poked on ahead a bit. That’s when I heard him ask, “What kind of spider is that?”
I was shocked to see him pointing at a small little triangle of walking tinfoil crawling through the webbing of some orbweaver. I had never seen this one before so I got very excited and managed to grab a few pics before it sscooted into a deep crack in the concrete wall
As soon as we got back home later, I had to drop everything and run to the computer to try and find a rough ID with iNat. And that’s when the lifer-ometer really started to flash and ding! What a rush (right?).
So these spiders apparently use their photonic adaption to reflect light that can attract moths and other night flying insects. But the spiders are too small to do anything with larger insects – but that’s okay because their um, weblords?
That is, the makers of the webs that they live in, are NOT too small to handle the larger prey. Which is why the larger hosting spiders don’t simply eat the little dewdrops. The little spiders pay their rent by adding their light ‘beacons’ to the game.
In exchange, they have decent shelter and access to smaller bugs that get trapped in the host’s webbing, but are too small for the larger spiders to be worth the effort of consuming. Crumbs.
An amazing inter-species collaboration. And later I read that it has been observed that what also can happen is that as this relationship matures, a sense of complacency can develop that culminates in the smaller spider actually growing to a size large enough to sneak up and kill the larger one while it is resting(!).
If this was a mini-series, would I find myself binging my way through it?
Absolutely.
Is it a male or female? I can’t tell.
