But Are They Real Worm's?
FROM THE DESK OF THE BUG DOCTOR - OFFICE OF WIGGLE AND SQWIRM - N.W. QUAD
Chironomids are " Non-biting " midge's from genus Chironomus. This is a "Stillwater" Trout's main food source! The larve are a "worm like" burrower ranging in color from light green, olive, to brown and red. The later being Chironomus Plumosus, known as the "Blood worm", but NOT a true worm!
This Chironomids color comes from the high amount of Hemoglobin that allows it to live in the Oxygen poor silt at the Lake bottom. When these midges pupate ( as quickly as 2 to 3 days ) they do so in the silt, then float to the surface as adults ranging in size from 1/32 to 1/2 inch. Adults have 2 wings and are colored brown, black, or green.
If you use "Blood worms" it is my opinion that your spot in FFH is secure, regardless of any other faults you might have.
