    "behavior": "Caddisflies flutter and hop across the surface during evening ovipositing behavior, touching down repeatedly to deposit eggs while maintaining flight-ready posture. The low-riding adult profile and erratic surface wake during prime evening hours concentrates feeding activity, with trout positioned in riffles and runs where egg-laying females create the most commotion during their upstream flight patterns."

  "behaviorPresentation": "**Natural Behavior**: Caddisflies in their critical emergence moment flutter weakly at the surface with wings half-unfurled, hopping forward in short bursts as they attempt to gain flight altitude. These low-riding emergers remain in contact with the water for several seconds, creating a vulnerable window when they are neither fully aquatic nor successfully airborne.\n**Where Trout Eat It**: Fish hold in highly oxygenated riffle water where caddis pupae ascend, targeting the low-riding emerger profile when emergence is slowed in cold tailwater conditions.\n**How to Fish It**: Fish drag-free drift through riffle water, though you can add subtle rod-tip twitches or slight retrieves. The two-toned body triggers selective trout refusing standard elk hair patterns.\n**Best Water**: Focus on riffle heads where oxygen levels are highest and pressured tailwater seams with complex currents.\n**Strike Type**: Gentle sips or confident boils mark feeding—watch for head tilts and surface disturbances.",
  "fishingStrategy": "**Rigging Suggestions**: Use 9-foot leaders with 5X or 6X tippet for natural presentation. Floating line in all situations.\n**Seasonal Timing**: April through October, peaking during June and July when caddis hatches are most prolific. Evening hatches are especially productive in late afternoon.\n**Pro Tips**: The deer hair wing provides excellent visibility and buoyancy. Watch for swirling rises that indicate caddis activity. Apply floatant to maintain high visibility throughout the drift.",
  "overview": "The EC (Emergent Caddis) features a sparse deer hair wing, dubbed thorax, and trailing shuck. It sits low in the water, imitating a caddis emerging from its shuck. The down-wing construction and clean silhouette make it perfect for picky trout in slower water."
