Stick Insects and Leaf Insects
Latin: Phasmida — Relevance to Fly Fishing:
Phasmatodea, consisting of stick and leaf insects, are known for their impressive camouflage abilities, mimicking plant parts to avoid predators.
Where you can find Stick Insects and Leaf Insects
On this map you see where there were observations of Stick Insects and Leaf Insects around the world. This will give you an idea of the global distribution of this class. Note that a class can have many different families, and thousands of species.
Diversity and distribution
The insect class Phasmatodea, commonly known as stick insects and leaf insects, consists of over 3,000 known species. These insects are characterized by their remarkable camouflage, as they have evolved to resemble plant materials such as twigs, sticks, and leaves. Phasmatodea is divided into several families and genera, with some of the most well-known families being Phasmatidae (stick insects) and Phylliidae (leaf insects).
Phasmatodea insects can be primarily found in tropical and subtropical regions. Their distribution extends across North and South America, Africa, Asia, and Australia. Phasmatodea species typically inhabit forests and other environments rich in vegetation.
Life cycles of Phasmatodea
The life cycle of Phasmatodea insects consists of three stages: egg, nymph, and adult. The duration of each stage varies among species and can be influenced by factors such as temperature, humidity, and food availability.
Female Phasmatodea lay their eggs on the ground or in 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 Phasmatodea insects.
Phasmatodea and fly fishing
Phasmatodea insects, while fascinating in their own right, are not typically relevant to fly fishing. Their primary defense mechanism, camouflage, makes it unlikely for them to be easily noticed by fish. Furthermore, their herbivorous nature and arboreal lifestyle mean that they rarely end up in the water, reducing their potential as a food source for fish.
It is worth noting that while Phasmatodea-inspired flies are not commonly used in fly fishing, it is always possible that a curious or opportunistic fish may be enticed by an unusual or rare food item. If you happen to find any of these stick insects near the water, try to match them with a generic, slim bodied dry fly pattern.
