"Earwigs Unveiled: Their Global Diversity, Life Cycle, and Surprising Role in Fly Fishing"

Latin: DermapteraRelevance to Fly Fishing

Earwigs are insects recognized for their pincer-like cerci and the widespread myth that they crawl into human ears.

Where to Find Earwigs

The map below shows global observations of earwigs, illustrating their widespread distribution. Note that the order Dermaptera includes numerous families and thousands of species.

Diversity and Distribution

The insect order Dermaptera, commonly called earwigs, comprises around 2,000 known species. These insects are distinguished by their elongated bodies and forceps-like cerci at the abdomen’s tip. Dermaptera is divided into roughly 12 families, with Forficulidae being the most well-known.

Earwigs inhabit diverse environments worldwide, including forests, grasslands, and urban areas. Their range spans North and South America, Europe, Asia, Africa, and Australia.

Life Cycle of Earwigs

Earwigs undergo four life stages: egg, nymph, and adult. The duration of each stage varies by species and is influenced by temperature, humidity, and food availability.

Females lay eggs in soil or leaf litter, depending on the species. Nymphs hatch and feed on plant matter, fungi, and small insects, molting several times before reaching adulthood. Adults maintain similar diets and are primarily nocturnal.

Earwigs and Fly Fishing

While not a primary fish food source, earwigs near water may attract opportunistic fish. Fly fishers can benefit from carrying patterns that imitate these insects:

  • Earwig Patterns: Designed to replicate the insect’s elongated body and cerci, these flies feature slim bodies and tail-like appendages, often tied with dubbing and hackle fibers. Though uncommon, they’re useful in areas where earwigs are prevalent.
  • Nymph Patterns: Similar to adult patterns but adjusted in size and color to match local nymphs. Many existing nymph flies can effectively imitate earwigs with minor modifications.

Including a few earwig-inspired flies in your box could prove advantageous in the right conditions.

"Thrips Unveiled: Tiny Insects with a Big Impact – And Their Surprising Fly Fishing Connection"

Latin: ThysanopteraRelevance to Fly Fishing:

Thrips are small, fringed-winged insects that feed on plants and occasionally transmit diseases, posing a threat to agricultural crops.

Where to Find Thrips

The map below shows global observations of thrips, highlighting their widespread distribution. Note that this class encompasses numerous families and thousands of species.

Diversity and Distribution

The insect class Thysanoptera, commonly called thrips, includes roughly 6,000 known species. These tiny insects are distinguished by their fringed wings, asymmetrical mouthparts, and slender bodies. The class is divided into two suborders: Terebrantia and Tubulifera, each containing multiple families and genera.

Thrips thrive worldwide, inhabiting diverse environments such as forests, grasslands, and farmlands. They feed on plant tissues, pollen, or occasionally small insects.

Life Cycle of Thrips

Thrips undergo four developmental stages: egg, larva, pupa, and adult. Females deposit eggs inside plant tissues, where larvae hatch and feed on plant cells, pollen, or tiny insects. After two larval stages, they enter a non-feeding pre-pupal phase, followed by the pupal stage. Adults emerge and continue feeding, depending on the species.

Thrips and Fly Fishing

Due to their small size and terrestrial habits, thrips are rarely relevant to fly fishing. While some species prey on small insects, their primary diet consists of plant matter, which holds little appeal for most fish. Additionally, thrips seldom end up in aquatic environments.

Scorpionflies (Latin: Mecoptera) – A Unique Insect with Fly Fishing Connections

Scorpionflies are distinctive insects with elongated bodies and beak-like mouths. Some species exhibit a scorpion-like appearance due to their modified abdomens.

Global Distribution of Scorpionflies

The map below highlights observations of scorpionflies worldwide, offering insight into their distribution. Note that the class Mecoptera encompasses multiple families and thousands of species.

Diversity and Distribution

The insect order Mecoptera, which includes scorpionflies, hangingflies, and their relatives, comprises approximately 600 known species. These insects are characterized by elongated bodies, membranous wings, and prominent beak-like mouthparts. Key families include:

  • Panorpidae (common scorpionflies)
  • Bittacidae (hangingflies)
  • Meropeidae (earwigflies)

Mecoptera species thrive primarily in temperate regions across North and South America, Europe, Africa, Asia, and Australia.

Life Cycle of Mecoptera

Mecoptera undergo three developmental stages: egg, larva, and adult. The duration of each stage varies by species and is influenced by environmental factors such as temperature, humidity, and food availability.

Females deposit eggs on or near their preferred food sources. After hatching, the larvae feed and molt repeatedly, resembling caterpillars or beetle larvae. Upon reaching maturity, they pupate and metamorphose into adults.

Mecoptera in Fly Fishing

While adult scorpionflies are not a primary food source for fish, their larvae may occasionally attract trout and other insectivorous species. For fly fishers, observing and matching the size and color of these larvae can enhance success. Explore local habitats to identify potential patterns!

"Caddisflies: The Ultimate Guide for Fly Fishing Enthusiasts"

Latin: TrichopteraRelevance to Fly Fishing

Caddisflies are aquatic insects closely related to moths. Their larvae construct protective cases using materials from their environment, making them a fascinating subject for anglers.

Global Distribution of Caddisflies

This map shows where caddisflies have been observed worldwide, illustrating their broad distribution. Note that the Trichoptera class includes numerous families and thousands of species.

Diversity and Distribution

With over 14,500 species, caddisflies are classified into 45 families and approximately 600 genera. They inhabit every continent except Antarctica, thriving in freshwater environments such as rivers, streams, and lakes—particularly in temperate and tropical regions.

Life Cycle of Caddisflies

The caddisfly life cycle consists of four stages:

  1. Egg – Females lay eggs on or near water.
  2. Larva – Larvae build protective cases from sand, twigs, or small stones, bound by silk. They feed on algae, decaying plants, and small aquatic organisms, molting several times as they grow.
  3. Pupa – Larvae seal themselves inside their cases to undergo metamorphosis.
  4. Adult – Adults emerge at night, live briefly (a few days to weeks), mate, and lay eggs to restart the cycle.

Caddisflies in Fly Fishing

Caddisfly imitations are crucial in fly fishing due to their abundance and role as a key food source for fish.

Larval and Pupal Patterns

Since caddisflies spend most of their lives as larvae and pupae, these imitations are highly effective:

  • Larval patterns (e.g., Green Rock Worm, Caddis Larva) mimic larvae.
  • Pupal patterns (e.g., Sparkle Pupa, Deep Pupa) imitate emerging pupae.

Adult Patterns

Used during hatches, popular adult imitations include:

  • Elk Hair Caddis
  • Goddard Caddis
  • "Caddisflies: The Ultimate Guide for Fly Fishing Enthusiasts"

  • X-Caddis

Flies Imitating Caddisflies

Given the vast diversity within the Trichoptera order, fly patterns vary widely, targeting different species and life stages (larva, pupa, adult).
