Eggs. Glo bugs or emerging trout imitations. However you want to look at them, love 'em or hate 'em they can certainly do the job. I don't often use egg patterns but when I do, its to get things moving and as such, keep a variety in my box. Here are a few personal thoughts and approaches for fishing Manic egg patterns.
Im personally a fan of yarn type egg patterns for their look and durability. However in still / soft water situations where fish get alot of time to 'mouth' the pattern before the indicator drops, then the realistic feel of the 'soft egg' range comes into their own resulting in fewer dropped flies.
GLO BUG: Sz10-14
The Quintessential yarn egg pattern with many variations. Colours: use brighter patterns in low light, morning or evening and coloured water, and smaller, more natural colours in lower, bighter or clearer conditions.
Baby Blue / Orange
Early Girl / Cherise
Late McRoe / Orange
Tangerine / Brite Red
Watermelon / Late McRoe
This is the yarn egg with punch. Lead eyes add the weight required if you need to get down on a one fly rig, where snags or structure prevent a two fly presentation. Also handy as an attractor to get a smaller, natural fly down.
ULTIMATE EGG: Sz14
A small, yarn egg with a veil simulating a freshly fertilised egg with the milt trailing behind, or slime covered decomposing eggs in the latter stages. The veil adds translucence to this pattern and shines when wet. A killer of a pattern.
Baby / Blue
OTTERS SOFT EGG: Sz12-14
These are an winner all round. Ultra realistic to the eye with the egg vail trigger. The benefit of soft eggs are that they feel natural to the touch, and thus aren't often ejected as quick a solid bead, or yarn type fly as mentioned above.
SIMON'S IRON MAIDEN: Sz12-16
Ok, so not an egg pattern however by nature many glo bugs are tied from rather buoyant yarn, the type often used as indicator material due to its floating properties. To get yarn eggs down into the bingo zone you'll need weight, often lots of weight and what better pattern to plunge deep than Simons Iron Maiden.
Green / Red
