Freshly Moulted Katydid.

 

Ecdysis is the process of shedding the old skin (in reptiles) or casting off the outer cuticle (in insects and other arthropods).

"Insects in the cricket family Tettigoniidae are commonly called katydids or bush crickets. More than 6,400 species are known. They are also known as long-horned grasshoppers, to distinguish them from the Caelifera, the true or short-horned grasshoppers. Part of the suborder Ensifera, it is the only family in the superfamily Tettigonioidea.

Primarily nocturnal in habit, with strident mating calls, many katydids exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves.

The name is derived from the genus Tettigonia, first described by Carl Linnaeus in 1748. Latin tettigonia means leafhopper; it is from Greek tettigonion, the diminutive of the imitative (onomatopoeic) τέττιξ, tettix, cicada.

Tettigoniids range in size from as small as 5 to as large as 130 mm. The smaller species typically live in drier or more stressful habitats which may lead to their small size. The small size is associated with greater agility, faster development, and lower nutritional needs. Tettigoniids are tree-living insects that are most commonly heard at night during summer and early fall. Tettigoniids may be distinguished from the grasshopper by the length of their filamentous antennae, which may exceed their own body length, while grasshoppers' antennae are always relatively short and thickened.

The lifespan of a katydid is about a year, with full adulthood usually developing very late. Females most typically lay their eggs at the end of summer beneath the soil or in plant stem holes. The eggs are typically oval-shaped and laid in rows on the host plant. The way their ovipositor is formed relates to its functional adaptability in the areas which it lays eggs. The ovipositor is an organ used by insects for laying of eggs. It consists of a maximum of three pairs of appendages formed to transmit the egg, to prepare a place for it, and place it properly. Tettigoniids have either sickle-shaped ovipositors which typically lay eggs in dead or living plant matter, or uniform elongated ovipositors which lay eggs in grass stems. When tettigoniids hatch, the nymphs often look like smaller versions of the adults, but in some species, the nymphs look nothing at all like the adult and rather mimic other species such as spiders and assassin bugs, or flowers, to prevent predation. The nymphs remain in a mimic state only until they are large enough to escape predation. Once they complete their last molt, they are then prepared to mate." - Wikipedia
