Grasshoppers, Crickets, and Katydids

Diversity and distribution

The insect class Orthoptera, commonly known as grasshoppers, crickets, and katydids, is a diverse group of insects consisting of over 20,000 known species. These insects are characterized by their large, hind jumping legs, elongated bodies, and often striking coloration. Orthoptera is divided into two main suborders: Caelifera (grasshoppers and related species) and Ensifera (crickets, katydids, and related species), with numerous families and genera within each suborder.

Orthoptera insects can be around the world, primarily in temperate and tropical regions. They are distributed across North and South America, Europe, Africa, Asia, and Australia. Orthoptera species typically inhabit a variety of environments, including grasslands, forests, and agricultural areas.

Life cycles of Orthoptera

The life cycle of Orthoptera insects consists of three stages: egg, nymph, and adult. Female Orthoptera lay their eggs in soil or plant material, depending on the species. Upon hatching, the nymphs feed on plant material and undergo several molts as they grow. Once they reach their final nymphal stage, they undergo one last molt to become adult Orthoptera insects.

Orthoptera and fly fishing

Orthoptera insects, particularly grasshoppers, are relevant to fly fishing due to their prevalence in terrestrial environments near water sources and their role as a food source for fish. Some well-known Orthoptera flies that are targeted by fly fishers include:

• Grasshopper patterns: Grasshoppers are commonly found near water sources, and when they accidentally fall into the water, they become easy prey for fish. You can use grasshopper patterns, typically tied with foam, deer hair, or other buoyant materials, to imitate these insects.
• Cricket patterns: Crickets are nocturnal insects that can also be found near water sources. You can use cricket patterns, often tied with dark colors and appropriate body shape, to imitate these insects during nighttime fishing sessions.
• Katydid patterns: Katydids, while less common than grasshoppers and crickets, can also be a food source for fish. Fly fishers can use katydid patterns with a slim body, large wings, and appropriate coloration to match the local katydid population.
