Hatchpedia

Hatchpedia is your pocket entomologist for fly fishing. It lets you identify hatching aquatic insects quickly, even without cell service, using a patent-pending search that interprets your words. The app offers offline functionality with a grace period after renewal, ensuring you won’t be stranded on the water.

Use Search by Example to build search phrases from photos and descriptions. Hatchpedia provides curated photos of all key life stages and detailed bug data—common name, taxonomy, size, US hatch regions, and hatch dates—plus lifecycle insights for every phase. The search engine handles simple keywords to complex phrases without special characters, and it can use your location and date to help plan trips and improve identifications. A free version is available to explore lifecycles and behaviors. Join the community and elevate your angling with precise, field-ready information.
