Steve Moulton: Caddisflies 101 for the Fly Fisher

Steve gave an awesome presentation tailored to fly fishers and conservationists featuring information about the diversity, biology, and ecology of caddisflies. It was most informative and we thank Steve for sharing his time and knowledge about caddisflies with us.

Caddisflies are one of the most important insect groups known to flyfishers. There are approximately 1,700 species of caddisflies in North America with the World fauna variously estimated between 10 and 50 thousand species; over 300 species have been documented from MD and VA. Caddisflies play an extremely important role in aquatic ecosystems by processing organic material and serving as a food base for other animals. They occur predominantly in springs, streams, rivers, ponds and lakes throughout the world. However, a few species are terrestrial throughout their entire life cycle and one group inhabits marine waters. Despite occupying a wide range of aquatic habitats, caddisflies are generally intolerant of poor water quality and stressed environmental conditions. As such they are often used by water resource management agencies as indicators of the aquatic health.

Caddisflies undergo complete metamorphosis with four life stages (egg, larva, pupa, and adult). Excluding the egg stage, fly fishers pattern flies imitating each stage that range in size from approximately 2mm (No. 24 or 26 size hook) to over 40 mm (No. 4 or 6 size hook). The grand challenge of fly fishers is to ”match the hatch“ by presenting a fly that imitates the life stage fish are mostly likely to prey on. Caddisfly larvae are best known for their architectural behaviors using of silk to build retreats, feeding nets, and portable cases. Larvae are soft-bodied and usually cream-colored or greenish with a darker-colored head and thorax (segment of body possessing the legs). Depending on geography, habitat, and temperature, caddisfly adults can emerge year-round. Some species (e.g., grannoms or Mother’s Day Caddis) develop and emerge synchronously in large swarms for a one or two week period usually in the spring or fall. Most other species develop and emerge at different rates such that adults are found almost year round.

Dan Boward, Maryland DNR

Dan gave an really interesting summary of the Maryland Biological Stream Survey Program at our Chapter meeting. The Maryland Biological Stream Survey (MBSS) collects fish, benthic macroinvertebrates, other fauna, land use and water quality information from streams in Maryland to develop a Stream Health Index for both fish and benthics. Since the program began in 1995, there has been a total of 5,833 sites surveyed through 2016. The surveys have found an increase in “good” stream conditions since 1995, with the percentage of stream rated “poor” about the same. There has been a decline in stream rate “fair” over the period. The MBSS is the sponsor of the Maryland Stream Waders Program, a volunteer based stream assessment effort to help educate and enhance stream stewardship. Information about streams sampled, the Stream Waders Program, and the MBSS may be found at or by contacting Dan directly at If you missed this meeting you missed an opportunity to learn about Maryland streams.

Dave Cleaves, Retired Climate Change Advisor to the Chief of the US Forest Service
Dave talked with us about the role of outdoor enthusiasts and citizen conservationists in dealing with the changing climate.

He discussed how outdoor recreation groups are doing to address and adapt to the changing climate.

Dave has provided an extensive list of sites that deal with this issue. You can get it here, or find it under Quick Links.
