I recently read an article on corixa which mentioned that this under used fly
can be deadly in stillwater.
it also claimed that this is, probably the hardest insect to tye a real looking copy.
You corixa anglers out there, what is your favorite pattern and size.
and also method of fishing this creature.
i did tye a pattern years ago but never had any luck,
but maybe i fished it wrong.

A Silver Invicta is as good as anything else Laurie, the sliver body suggesting the ball of gas that the corixa carries around. Around weed beds, where the corixa are most concentrated the Silver Invicta will also suggest pin fry, sedge pupa etc. Can't go wrong! If you want to go more imitative then a weighted close copy 'nymphed' will get you results.

fished the corixa alot trying... to get a picture up but the link wont work...kamasan B170-175 size 12-14 weight hook with silver wire til you get a nice buggy shape, keep silver wire on for rib.tie in 5-6 pheasant tail hurls(for back)tie in fine silver tinsel. coat silver wire with varnish and wind silver tinsel down body with touching turns,rib with wire lay pheasant tail over back and tie down,take two peasant tail hurls and run varnish down them with your index finger and thumb to strengthen them. tie them in one each side.tie a neat head to finish.go fishing, tie it on ,cast it out and retrieve it with a jerky lil' figure eight retrieve interspersed with one inch pulls

Always thought it was to represent a May-Fly Nymph or bug, also the Beetle with the same name.

A silver or preferably pearl bodied nymph wiht pheasant tail fibres tied over as a back and then the ends tied facing backwards as legs - or even a standard p/t nymph with a silver or pearl thorax.
Fished slowly around the edges of weedbeds, sink and draw retrieve.

Hi,

I fish a black or brown corixa on a regular basis, and find it quite successful.

Last friday I had 2 fish on a black corixa, and a number of other fish that took the buzzers (black & silver) that I tend to fish above.

I find the slightly weighted corixa on the point helps me to keep in contact with all the flies, and whether the fish mistake it for a black and silver buzzers I'm not really bothered, however, a corixa catches fish for me on a regular basis when fished on the point, and when fishing either buzzers or hare ear nymphs, etc, above it.

Mine are tied mainly with a black back, (but with a couple in brown), on a grub hook in size 10, with a gold-head or slightly weighted body.

The underbody is white thread with black or brown pheasant tail fibres tied in at the bend on the hook and then pulled across the back and held in place with a fine thin silver wire rib to stop the fibres from spreading out.

To form some legs I then gently split the fibres into 2 bunches and then push and lay then pointing from the eye of the hook to the hook point and then whip finish then in place so they form the legs, and simply trim to size. In the past I have varnished the fibres forming the back, but I tend not to bother if I using a fine wire rib.

Have a look at; http://www.diptera.co.uk/patterns/c/corixa_ti.html

On my version I stop the back fibres before the gold head if I'm using one, and then push and tie the fibres down the sides, I don't bother tying in a separate hackle, the legs pushed back provide plenty of attraction.

Tie a few up, and fish them on the point below nymophs or buzzers and I'm sure you'll soon catch on one!

Hi', Laurie. I used to tie corixa copies a good while back, both weighted and unweighted. Tied the unweighted flies the right way up, weihted flies upside down, to differentiate between the two. First dubbed a cream/off-white body; ribbed fine silver wire; dark, mottled wingcase (grouse or mallard) or black (crow) tied in at the back of the body and pulled forward to the shoulder, two long paddles tied in under thorax, using dark goose or heron primary barbs (fibres) knotted to make a 'foot'.Legs slightly longer than body.
Weighted flies had fine lead foil built up and bound on the top side of the hook, which made them swim upside down, so wingcase was tied in on the hook underside. A short dark brown hen hackle tied in at the head.
Ideally, corixae patterns should be fished in shallow marginal water, as the beetles live in water of a maximum depth of about four feet. They have to come up to the surface for air, hence the use of a silver tag to represent the bubble at the bum end. They would probably find it very difficult trying to swim down to a depth of over four feet, due to fighting against the buoyancy of their air supply. Fished around weed beds, they can work well, so can hoglice patterns, such as a chunky Gold-ribbed Hare's Ear, which looks better with a small brown or grey partridge hackle laid, over its back, secured with the wire rib, and overlaid with cover of grey goose primary strip.
Corixae probably best fished on the drop, or pulled to give a sink and draw up and down movement, while hoglice should be fished very slowly, pull and pause hard on the bottom. You can also fish buoyant hoglice to float up from the bottom, booby style, on longish droppers; but they must be fished pull and pause, or the trout will take them right back in the mouth, like they do with static boobies. Fished properly, these hoglice can be deadly when fish are grubbing in the debris on the lake bed, nose down and bums up.
But as has been suggested, some of the general purpose patterns, like Silver Invicta, cover corixae and fry. Nothing like hedging your bets. TC
PS Between us, I think Rob and I could kick a few fishy backsides.

There' s a good one on the SBS section by cowie, epoxy bubble corixa I think he called it, very easy to tie up too.

Joe,
I find invictas work, pearl/silver. As Rob says they imitate a few things.
Diawl bach tied with hare's ear body, not the usual herl also worth a go.

However if I think they are feeding on corixa I would put one of these on the point. Easy to tie, B160 hook 10-16, light under wire of lead (or substitute), cream thread body, pheasant tail back (from black through to light tan). Paddles made of the thread, marked at the tip with black pen. HAN the whole lot two or three times.



Long leader and if have a dropper on it would be a black diawl bach with holo red rib or a cruncher with gold cheeks. Keep varying the retrieve, a stop can be deadly.

There was an article in July T&S that had some nice muddled patterns. I'll be trying some of those.

Cheers,
Mark

I've caught with Corixa patterns, in shallow water, near reeds and weeds. I've used a buoyant one on point and a weighted one on the dropper. If you watch corixae swim they make short jerky dives and then float back a bit. If you try to imitate that in the retrieve it ought to work.
