Gurgler (Night Frog)

A

Foam-lipped gurglers and waking flies round out the Michigan night box per Mangled Fly, pushing a wake that big browns track in the dark. A black gurgler also works for a dark Hex or big caddis after the main hatch; strip it steadily across flats from June to mid September.

How it's tied
A
Gartside Gurgler (Night Frog). A single strip of foam folded into a lipped shellback over a palmered body; it spits and wakes on the retrieve and is the simplest night frog you can tie. Our own write-up of the standard tie, checked against the sources below. Recipe by Jack Gartside.

Materials

Hook
Mustad 34007 or 9674, sizes 2 to 6 (Gartside lists 4 to 2/0 in salt, 6 to 2 in fresh water); TMC 811S is Craven's choice
Thread
Danville 3/0 or Monocord, white for the light fly, black for the night fly
Tail
A very sparse bunch of bucktail or a marabou plume, one-and-a-half shank lengths, with 5 or 6 strands of pearl Glimmer or Krystal Flash over it
Body
One strip of closed-cell foam 1/2 to 5/8 in wide and at least 1/8 in thick, tied down in five even segments (Craven adds pearl tinsel chenille under the hackle)
Rib
Saddle hackle palmered between the segments: white or grizzly, black or olive for the frog
Shell
The same foam strip pulled forward over the body and left standing about 1/2 in past the hook eye as the lip
Legsoptional
Rubber or silicone legs at the collar for the frog version
Adhesive
Head cement on the tie-downs and the final wraps

Steps

  1. 1.Start the thread at mid-shank and wrap back to the bend.
  2. 2.Tie in a sparse tail of bucktail or marabou about one-and-a-half shank lengths long, then a few strands of pearl flash on top of it.
  3. 3.Cut a foam strip, trim one end square and tie that end down on top of the shank at the tail, leaving the long end hanging back 2 to 3 in behind the hook.
  4. 4.Tie in the saddle hackle by its butt at the same point.
  5. 5.Advance the thread a fifth of the way up the shank, fold the foam forward and take two or three wraps over it, then advance again and repeat until you have five even segments (or wrap a chenille body and simply palmer the hackle).
  6. 6.Bring the hackle forward in open spirals between the segments, tie it off behind the eye and trim.
  7. 7.Pull the remaining foam forward over the top of the body under light tension and bind it down just behind the eye.
  8. 8.Stand the foam up, take a few wraps in front of it to keep it upright, and cut the shell off about 1/2 in past the hook eye to make the lip.
  9. 9.Add legs at the collar if you are tying the frog, one or two strands each side, sweeping back.
  10. 10.Whip finish under the lip and cement the wraps front and rear.

From the tier

  • Jack Gartside ties it in white, yellow and black but says the fish do not much care about colour; the colour is for you, so you can see the fly. He fishes his Trout Gurgler on smooth water: cast it out and bring it back with twitches and gurgles. He notes that anglers on the Au Sable rate it highly for big trout.
  • Night Frog notes from Michigan: Ed McCoy classes gurglers among the flies that float high and throw a defined wake; cast tight to the bank and use popping strips. Max Inchausti (Flylords) keeps trout frogs slim rather than bass-bug bulky, casts 45 degrees to the bank on a 6 to 8 ft leader ending in 15 to 20 lb, and slowly strips as the fly swings.
  • Variants: black foam and hackle for dark nights, olive foam with a grizzly hackle and legs for the frog, natural or white foam with a white hackle for bass and dusk fishing.

Tying the Gurgler Steps summarize Gartside's original single-strip Gurgler with Craven's chenille body noted as an option; the Night Frog colours and legs are a Michigan adaptation, not Gartside's. Unconfirmed: Gartside's own pages do not show a publication year; the name Night Frog for a dark trout Gurgler was not traced to a single Michigan shop. Also checked against Jack Gartside, Jack Gartside's Gartside Gurgler, Jack Gartside, Jack Gartside's Trout Gurgler, Charlie's Fly Box (2022), Gartside's Gurgler, Ed McCoy, Mangled Fly (2021), Night Fishing - Mousing for Trout - Northern Michigan and Max Inchausti, Flylords (2026), Frogging, the Other Night Fishing.
