Green Drake

Recently going through my mayfly photographs I found a nice set of pictures from the Paflyfish Spring Jam in 2010. The Green Drake (Ephemera guttulata ) hatch was in full swing that year and photographs of these mayflies was easy and plentiful. Most of the weekend was overcast and rain as normally forecasted for the Spring Jam. Emergers (subimigo) and spinners (imago) were not so much active during the day, but lined the sides of the streams in the hundred's of thousands. I am always torn between fishing and photography on days like this but glad put down my fly rod for a while and captured a lot of great shots.

With so many mayflies and photos it was easy to get so nice shots of the Green Drake spinners, which are referred to as Coffin Flies because of their white extended body. I wanted to demonstrate the differences between spinner (imago) male and female. These two Coffin Flies attached show these differences. Most notably the male has longer extended fore legs and claspers at the rear of the body. Females as seen do not have these body characteristics.

Male (left photo)
Long fore legs
Rear claspers or forceps at rear of body
Eyes on a male tend to be larger

Female (right photo)
Short fore leg
Forceps do not exist
Smaller flatter eyes

Trout enjoy a wide array of food and insects being the more popular. While mayflies (Ephemeroptera) enjoy much of the spotlight, caddisflies (Trichoptera) are incredibly plentiful in waters across the region. Not always the preferred insect of the fly anglers mostly due to lack of familiarity.

caddisflyCaddis are a hardy insect and has thrived in streams that have been decimated with pollution. Streams like the Tulpehocken, Oil Creek and Casselman are are just a few streams known for their abundant caddis fly populations in our region. For many of these streams the caddisfly is so prolific that mayflies are an often afterthought for anglers.

The caddis behavior is a little less predictable and is certainly one of the reasons it is not as popular for many anglers. Many mayflies can be timed to within a few days and hours. The Green Drakes on Penn's Creek are revered by anglers the same way the "Swallows" of Capistrano are anticipated at the Mission San Juan Capistrano. Caddis not so much.

That is not to say great hatches of caddis are not enjoyed by anglers and trout, as there can be wonderful evenings and days with them covering a stream. Just as often there can be sporadic emergers happening with without much fanfare.

There are over 1200 species of caddis flies in the country. They range in size and colors covering the gambit of black, green, tan, cream and white bodies. The more popular Grannom hatch do arrive across much of the region at the end of April and are much anticipated by anglers and trout alike.

To get some understanding of their cycle it is as easy to do as by simply lifting a rock the next time out on the water.

caddisflyMany types of caddis larvae can be found at the bottom of the stream in self-made protected cases or roaming along the bottoms of streams. Some these species create protective cocoons made of small stones or sticks held together with silk like threads. This thread is also used to secure the larvae to the larger rocks or stream bed where they live.

As the caddisflies mature they reach the pupa stage were they hold-up inside their cases and prepare to emerge out as adults above the water. This transformation from water to wing is the most dangerous for all insects. The caddisfly rise from their cases often with the help of a small gas bubble pulling them towards the surface. Once there they emerge with their uniquely folded tent-style of wings they take flight.

The caddis return to lay their eggs either on the surface or by diving to the bottom depending on the species. Like when they emerge, this is the time when they are most susceptible to hungry trout. The cycle of life then returns as these eggs transform into the larvae again.

Like mayflies, caddis flies begin in ernest in April and are big part of many streams. Continued sporadic hatches can be found through the late Fall.

A mayfly hatch is the grand finale in the year long seasonal play that returns annually for trout and anglers.

MayFly StagesThis show begins the previous season with mature female mayflies, called spinners, laying their eggs on the surface of the water(video). The eggs shortly hatch into small larvae and quickly change into nymphs.

The nymph phase of the mayfly is the longest and will last just about one year. Different species of mayflies can be found in different parts of a stream. Some prefer the faster water and rocks, while others are only found at the end of pools in deep mud. During this time a nymph will grow and molt regularly. Molting is when the mayfly breaks out of it's old skin and a larger one is exposed underneath to protect it during the next growth cycle. During the final molting these leftover soft shells are referred to as shucks.

The emergence stage out of the water can be a quick and dangerous time for these transitional nymphs. Trout can find and aggressively feed on these insects that normally may be hiding or burrowing at the bottom of a stream. Once ready to leave the water the hatch begins. The emerger swims to the surface film molts their skins and expose there wings.

Green Drake Spinner aka Coffin FlyThe cloudy, grayish wings they emerge with give them there name: dun. The duns sit on top of the water and prepare its wings for flight. On top of the film of a stream they ready their wings for flight. This can take seconds or minutes depending how fast the mayfly can take flight. During this phase, mayflies often can been seen in great numbers sailing down the stream with trout striking on an easy food source. Once the dun escapes the water, it will head for the trees for several days.

While maturation occurs during this stage a dun may molt several more times until it becomes a spinner (Green Drake spinner aka Coffin Fly pictured left). As spinners they have no mouths to feed, male and female mayflies will seek each other out only to mate. The females will quickly lay her eggs back at the water starting the cycle over again.

The cycle ends when the dead and dying mayflies drop to the stream. The spent wing spinner is the one final opportunity for tout to feed on the last stage of this great yearlong production provided by the mayfly.

There are thousands of streams across the region where wild trout naturally reproduce as a result of ideal water conditions and the availability of food. With countless years of evolution behind them, trout have successfully learned to eat a wide variety of food sources. Even then for the trout, everything from geology to pollution influences what kind of trout food prevails in each stream. Stocked trout are no exception to this and within days when they are placed into streams instincts quickly kick in for them to key in on naturally occurring trout food.

These different types of trout foods may not only be specific to a stream, but seasonal as well. Trout are limited to what is presented to them much like many animals in the wild. Typically spring and summer offer a great abundance of food choices. Winter may only provide limited food supplies. Trout adapt to the cold water by naturally reducing their metabolisms.

Familiarity with the different food sources is one of the fundamentals of successful fly fishing. Let's have an overview of these trout foods.

Aquatic Insects - mayflies (Ephemeroptera), caddisflies (Trichoptera), midges (Diptera), and stoneflies (Plecoptera)
For many, fly fishing is centered around the life cycle of aquatic insects as much as it is the trout's themselves. Many anglers unwittingly become pretty good entomologist in pursuit of fly fishing. These insects are a significant part of any trouts diet throughout the year. For most aquatic insects they live almost 98% of their lives in the water. Trout will feed on these bugs during all times of the insects life cycle. Most notably trout will key in on active or passing nymphs in the water. For a brief period at the end these insect's life they hatch from the water to mate, lay eggs and die.

For many fly fishing anglers, mayflies are the belle of the ball and can be found hatching in significant numbers from April thru July. They are found during all times of the year, but just more sporadically. Under the correct conditions, a few streams even have small occasional hatches of blue-winged olives (BWO) in the dead of winter.

Midges, stoneflies and caddisflies are very common in streams and have similar life cycles. Specific behavior with all these insects can vary greatly beyond the living, molting, emerging, mating and dying cycle. Certain types of caddis live under rocks with little wooden stick homes protecting them, while some mayflies burrow deep in the muddy ends of pools rarely being seen until they emerge. There is a lot of diversity and behavior between these insects that should be understood.

Fish - small trout, minnows and sculpins
A wide variety of small fish can be considered part of a trout's diet. There are many types of smaller fish including young trout, darters, minnows and sculpins that are trout favorites. Habitat and water conditions influence which type of small fish patterns are the most successful.

Terrestrials- ants, beetles, grasshoppers and caterpillars
These are all those bugs that don't live in the water, but can be found by late spring thru the fall landing in the water as trout food. About any insect that can fall off the banks or out of a tree can find itself in trouble with actively feeding trout. I have seen trout gorge themselves on caterpillars falling out of trees in June, but also quietly picking off ants by the edge of a stream in September. Out west grasshoppers are all the action during late July and August.

Crustaceans (Crustacea)- crayfish , freshwater shrimp and scuds
While crayfish are very common, scuds and shrimp are more often found in nutrient rich streams with abundant plant life in limestone fed waters. Scuds and shrimp need this type of habitat to survive. In limestone streams trout can be seen nosing into the weed beds feeding on these scuds. Crayfish can thrive pretty well in streams with just rocks and modest bottom structure.

Mammals - mice and other small rodents.
Trout can be pretty aggressive predators. On some streams, larger trout can key in on a mouse swimming across a stream that they can easily prey on. Anglers will typically try this approach in the evening since rodents are generally nocturnal creatures.

Fish eggs
Trout and other fish deposit eggs during their spawning seasons. Trout will commonly follow up behind these spawning fish and take advantage of this opportunity to get an easy meal. Sucker fish spawn in late winter and very early spring. Rainbow trout spawn in the spring, with brook and brown trout spawning in the fall.

Centerpins Permitted on C&R FFO Areas?

Resized ImageThis past January the Pennsylvania Fish and Boat Commission (PFBC) Commissioners were asked to expand opportunities for anglers across the state. A New Rule Making Proposal #264 just hit the PF&BC page.

It is named the Simplification and Consolidation of Regulations.

Many of the 9 major item categories involve mundane Summary Book Changes to language, semantics on baitfish, size, lake regulations, elimination of the WBTEP program, etc. But one change in particular may be of interest to followers of this page.

#8
In § 65.14, {C&R FFO Areas} the Commission proposes that the reference to single hooks be removed to clarify that multiple hooks are permitted. The Commission also proposes that the reference to “flyline with a maximum of 18 feet in leader material or monofilament line attached” be removed to eliminate a gray area regarding center-pinning techniques, which is becoming a popular technique to fish nymphs and utilizes a much longer leader.
To eliminate confusion and having to name or describe all prohibited lures and substances, the Commission further proposes deleting the list of prohibited items in favor of naming the permitted lures and substances only.

View the whole proposal Here.

What are your thoughts on letting Centerpinning into FFO areas? This regulation change would suggests that Centerpin fishing is fly fishing. Fly fishing it the act of delivering the terminal fly using the weight of the line and leader to carry it. Centerpinning uses the weight of terminal tackle to fling the bait upstream.

The PF&BC have literally rewritten the definition of fly fishing with this one. We feel this is an unnecessary change to the Fly Fishing Only regulation and diminishes the integrity of fly fishing as a form of fishing. We clearly need to let our voices be heard. We have been encouraged to comment on this proposal so send a comment today. Please let the PFBC know you are opposed to the changes with a written letter or comment online.

...While increasing the length of the leader material to allow for Euro-nymphing is a reasonable change, eliminating Flyline from fly fishing areas is clearly a mistake and must be kept in the regulation to maintain the integrity of fly fishing.

Comment period is April 4 - May 4. Comment Here.

Letters: PFBC Executive Director John Arway, Pennsylvania Fish and Boat Commission, P.O. Box 67000, Harrisburg, PA 17106-7000.
