I am no entomologist so I wonder if anyone can identify this? There were thousands coming off the water at Great Falls today in the warm sun.

stonefly... good to see! 

even with the adults popping on warm days i still fish an emerger/nymph pattern unless you see fish rising.

Oh that's cool!  I didn't know we had ANY EPT around here (ephemeropters. plecopters....and trichopters!)

I've never seen a stonefly nymph in any DC streams...and only 1-2 mayflies.  Thank you for posting this!  That's extremely cool.

Generally referred to as a winter stonefly. They will cover you during the shad run around chain bridge.

Being covered in stoneflies while fishing for shad is an experience I'd like to have -- when I moved here I had not even heard of "fishing" for shad as anything other than throwing a cast net to collect blue cat bait ;).  I gotta try it.

We have lots of all of these.  During the summer, I see large quantities of all three of these swarming parking
lot lights near a stream( that has water in it all year long).  I am not sure how many actually live in the potomac.
I also see the occasional fishfly (helgramite adult).  They are scarry looking beasts.

The water quality monitoring programs in Maryland (a number of organizations participate) do macro-invertebrate surveys in local streams.  Mayflies and stonefiles are an indicator of a healthy stream.  If all you find are diptera(fly) larva, the stream is less healthy.

Sure thing Carl -- I definitely believe it.  

I worked for DDOE for 2 years doing electroshocking and invert sampling on the DC streams (3 sections of rock creek, battery kemble, pope's branch, dalecarlia, watts branch, hickey run, etc.) and we commonly got aquatic worms, chrionomids, crane fly larvae, damselfly larvae, giant water bugs (belostomatids),  and literally only 1-2 mayfly larvae that I can recall.  

I know that the EPT = good water quality is a generalization since many species in those 3 orders are pretty tolerant.   The stone flies are usually called shredders right?  Or is that another group?  If I recall, there are 1 or more stonefly species that are predatory!  It's good to see that we do actually have some of those guys around here.  

Surprisingly, I don't recall ever kicking up a helgrammite -- but I know a lot of you have.  I'd love to kick one up some time.....I've always thought being bitten by a helgrammite would be interesting.  Those giant water bugs can apparently bite the crap out of you....like assassin bugs.

Oh, and diptera of course....like you said.  The crane fly larvae remind me of "tremors" ;).  Kevin Bacon man!

On the subject of bugs and more, Holmes Run below Barcroft has a plethora of bugs. I stocked my classroom fish tanks from that stream when I was a teacher. Everything from hydra (freshwater jellies), dapnia, planaria, (blue) crayfish, japanese trapdoor snails, generic snails, cress bugs, scuds, hellgrammites, green rock work caddis, and more. Loads of blue tailed skinks along the stream crossings too. I do most of my sampling below the 3rd crossing. As for being bit by a hellgrammite, I had one in my shoe that bit me back in 1993. I put it on a hook and caught 7 smallies on it before it broke apart. I had one get into my shirt and was on my stomach a few summers ago. Reminded me of the leech scene from Stand By Me.

The hellgrammites ate pretty much everything in my tanks.

Here are some images:

I will look for some more pics from around here. Cory Routh (kayak fishing book author)  told me that all the scuds in the water are a sign of poor water quality.

Wait - "blue tailed skink" is probably the juvenile coloration for the 5-lined skink ;).  -- http://en.wikipedia.org/wiki/Plestiodon_fasciatus

Cool pics Rob -- caddis, helgrammites and stoners all are a pleasant surprise to me!

When I did a recon of Holmes run - I waded it all the way down into
hunting creek to where that stocked lake empties into it (forget the
name) - back in November and for the life of me, I didn't see a single
insect let alone any kind of fish whatsoever. Absolutely nothing
alive. Which part of Holmes run are yall referring to?

Lane, I fish the section at Holmes Run III park below the lake Barcroft dam and below Columbia Pike.

Watch out for the Santeria.
