How to Fish PMD & Sulphur Hatches

PMD and Sulphur hatches are some of the most consistent mayfly events, often producing steady surface feeding and selective trout. Matching size, profile, and timing is key to success.

• Start with nymphs before surface activity begins
• Fish emergers as trout begin feeding just below the surface
• Switch to dry flies when trout are rising consistently

When PMD & Sulphur Hatches Occur

PMD and Sulphur hatches typically occur in late spring through summer and can last for extended periods on productive rivers.

• Most common from May through August
• Often strongest in late morning through afternoon
• Common on tailwaters and spring creeks

Fly Selection Tips for PMD & Sulphur

Trout feeding on PMDs and Sulphurs are often selective, especially on pressured water.

• Use smaller patterns (sizes 14–18) to match the hatch
• Downsize if trout are refusing your fly
• Emergers are often more effective than dry flies during heavy hatches

PMD & Sulphur Fly Quality & Construction

• Hooks: Chemically sharpened for consistent hook sets
• Materials: Fine dubbing and delicate profiles for realistic imitations
• Sizes: Consistent sizing for precise hatch matching
• Tested: Proven effective on technical trout water
