Microdry Series - Light Cahill Baetis

Product detailed description

Microdry Series - Light Cahill Baetis. Special micro dry fly patterns in natural insect colours, with genetic dry fly hackle on top. Works great on wary grayling and trout.

Baetis is a genus of small aquatic insects in the order Ephemeroptera, commonly known as the "blue-winged olive." Baetis nymphs are an important food source for fish, and Baetis mayflies are well-known to fly fishermen as one of the most important hatches in many streams and rivers around the world. The nymphs of Baetis species are typically found in slow to moderately fast-moving water, and they feed on algae and other small aquatic plants. When they are fully grown, they emerge from the water as winged adults, which fly to nearby vegetation to mate and lay eggs before dying. Baetis mayflies are often used as a model organism in aquatic ecology research because they are relatively easy to study and are an important part of many freshwater ecosystems.

The Microdry Series Light Cahill Baetis is an ultra-small dry fly designed to imitate tiny mayflies, duns and baetis insects. Its light cream body and subtle hackle create a natural surface silhouette for selective trout feeding on small emergers and duns.

Key Features

• Ultra-light microdry design for delicate surface presentation
• Light Cahill body imitates pale mayflies and baetis insects
• Fine hackle provides floatation and subtle movement
• Minimal profile for highly selective trout or grayling in clear water
• Natural coloration matches small surface insect hatches

Use Cases

• Dry fly fishing on rivers, streams, and stillwaters
• Targeting selective trout feeding on small mayflies and baetis
• Effective in calm water, low light, and technical fishing conditions

Technical Specifications

• Type: micro dry fly
• Material: synthetic thread, hackle fibers
• Color: light cahill (pale cream) body
• Sizes: micro (typically #18–#24)
• Buoyancy: natural (no floatant required or minimal use recommended)

Alternative Names / Synonyms
light cahill dry fly, baetis dry fly, micro mayfly imitation, no-see-um fly, trout surface fly

What Makes It Different
The pale cahill coloration combined with a micro-profile design creates a highly realistic imitation of small mayflies and baetis insects, making it especially effective for selective trout feeding on subtle surface activity.
