Episode 39: Pics and Patterns for Golden Stones

Angler's Entomology Podcast

Show Notes

As I mentioned on the podcast, if you are in the Southern Maine area, on Thursday January 9, we'll be having a fly tying demo at Joshua's Restaraunt in Brunswick, ME from 6 to about 8. Bring your fly tying material if you want (and a lamp) or just come and learn about these insects in person and their imitations. So, as I mention in the podcast, I'm referring to two families of stoneflies when I talk about "golden" stones - both Perlidae and Perlodidae. What draws them together is the fact that they have these tiger striped nymphs. Like this - where this one happens to be a Perlid:

One of the things that is distinctive about them is that you can often find their exuvia (discarded exoskeleton) on the rocks around a stream. This is a fun picture where not only do you see the exuvia of the Perlid stonefly, but exuvia of four other aquatic insects (including one on the Perlid) that hatched.

OK, so there are a ton of fun patterns that you can use to imitate these guys. Where it is worthwhile knowing that in both these families, not all members have this tiger striped pattern. Some are just plain brown or tan, and all these imitations can be adapted colorwise to match those stoneflies. Similarly, you can use all of these to imitate the generally smaller Perlodidae, where I would use a size 12-10 sized hook, or the larger Perlidae - 8-4 sized hook. So let's start with Charlie Brook's Montana Stone:

Hook: has to be pretty long - 2x or 3x. Tail: Biots Body: Brown yarn Rib1: Yellow yarn tied in at head, wound back and then forward in a crisscross pattern Rib 2: Gold wire - tied over yellow yarn Thorax Brown yarn Legs: Grizzly and brown hackle along with dun or white ostrich herl. Here is Polly Rosborough's Golden Stone imitation:

Tail: Yellow dyed mallard, or teal, or wood duck Abdomen: gold yarn or floss Shellback: Yellow dyed mallard, teal or wood duck Rib: Thick yellow thread, such as rod building thread Wingcase: Teal neck feather Legs Yellow dyed mallard, teal or wood duck Ok, then you get to my flies. Here is one I call Eric's Acroneuria, I like it because it is simple materials wise.

Tail: stacked yellow and brown (or black) deer hair or buck tail Body: wrapped butts of tail tied up to thorax Rib: Optional gold wire Wing case: butts of tail folded back and forward Legs: Butts of tail folded down and trimmed to length and density Head; Bead Or Eric's Rubber Stone:

Tail: Brown rubber legs Body: Yellow and brown rubber legs wound up to thorax Legs: Brown rubber legs Thorax: Brown dubbing Wing case: Burnt pheasant church window feathers Head: Bead Lastly, here is a simple fly that sinks well, Eric's Bead Stone:

Head: Copper Bead Body: Alternating yellow and brown glass beads Tail: Rubber legs Body: Rubber legs Wing case: goose quill doubled over twice You'll notice on some of these I have a single wing case and some a double wing case. Stoneflies, as you know, have two wing cases. When I tie one it is because I know the fish can't count. OK, for the adults, remember that all these stoneflies can hatch into adults with all sorts of color patterns. Some of the Perlodidae hatch into light colored adults - best imitated by a yellow sally type fly. While a lot of the other stones hatch into something more brown or tan in coloration. (Where sometimes the "tan" of the body can be rather yellow). To me there are two styles of stonefly adults that are worth tying - the active fluttering adult and the spent or drowned adult. I'll give examples of the fluttering adults first: So, let's start with a classic fly, the Sofa Pillow:

Tail; Elk (or deer) hair Body: yellow yarn or dubbing Rib: Brown hackle Wing: Elk (or deer) hair Hackle: Brown - tied full A similar great fly is the Stimulator:

Tail: Elk or deer hair Body: Yellow dubbing Rib: Grizzly or badger Wing: Elk or deer hair Thorax: Amber or orange dubbing Hackle: Grizzly or badger In terms of flies that sit more flush with t

A discussion of metamorphosis - focusing on simple metamorphosis as it relates to mayflies, stoneflies, and damsel and dragonflies. And of course rambles about the nature of change. I hope you enjoy.

Hey Everyone, Here are the pictures and patterns that are relevant to Part 1 on of metamorphosis - focusing in incomplete metamorphosis and the critters that do that. (Primarily mayflies, stoneflies and dragon and damselflies). First, though, as promised in the podcast, here is what a silverfish looks like. A little worse for wear - he's (or she) has been pickled for 8 years, so it's lost a lot of its color. Normally, they are a very silver color - hence the name. In some ways you may say this looks a little like a mayfly nymph. In real life, looking at them, you would not mistake them as being different.

Hey everyone. I hope you enjoy today's episode on black quills. I have some nice pics and patterns on the blog, so check that out too. Email me ([email protected]) if you want a guided entomology/fishing trip and get your loot at Selene's Fly Shop.

Hey everyone. Here is my blog post for Episode 54: Pics and Patterns for Black Quills. First let's take a look at the nymph. Here is a nice black quill nymph with a scale in centimeters. It is hard to see, but note the length of the antennae and the nice dark wing cases. That suggests he (or she) is likely to hatch soon. (Well, if he (or she) wasn't pickled in alcohol since 2003). Also fyi, this one was collected in a pond - which make sense, they migrate from moving water to still water to hatch. In contrast, the next specimen was collected in a stream, and you'll note the lack of developed wing pads (noting it was also collected earlier in the season).

Hey folks, hope you all enjoy part 2 of our discussion about how insects reproduce. Lots of wild stuff in this. And check out the blog - I added lots of cool pictures that are relevant to both episode 51 and 53. Enjoy!
