Tricos are an aquatic insect which shows up on eastern trout streams in early July. It's intensity and regularity make it an important food source for trout. The next few blogs will focus on this challenging but rewarding hatch.
Tricos start life as an egg. The eggs develop when the water temperature is fifty five degrees and above. Eggs laid last fall went dormant, or into diapause. This spring when the water temperature hit fifty five degrees again, they began developing again.
