Caedica simplex

Caedicia simplex

''Caedicia simplex'' is a species of bush cricket, native to New Zealand. It is also found in Australia. Its common name is the common garden katydid.

Species found in the family Tettigoniidae are differentiated from other ensifera by the presence of forewings that can be held away from the body modified to help with both leaf mimicry and acoustics, as well as the female ovipositor. Generally speaking, katydids have extremely long antennae in proportion to their body size, as well as a body that is cylindrical or laterally compressed with 3 sets of long, spindly legs that are used for long-distance jumping. Among all katydids, ''Caedicia simplex'' is considered an unremarkable species in appearance. The common garden katydid strongly resembles a small leaf in appearance with a grass-like, green coloration, measuring at about 4–6 cm as an adult. In the nymph stage, however, C. simplex are sometimes a vibrant red-pink color, lacking the leaf-like appearance of their adult counterparts. ''Caedicia simplex'' has a distinctly small, oval head with a velvety green appearance and bright, orange-red eyes. The velvety pronotum on common garden katydids are distinctly keeled, marked with a yellow stripe, having an anterior notched margin and a rounded posterior.

Due to the massive distribution of family Tettigoniidae species the habitats can vary highly from nation to nation. Within the context of New Zealand, it is immensely common in-home gardens hence its common name as well as more forested areas. The katydid usually stays near vegetation such as shrubs and plants so that it is able to properly camouflage itself as well as maintain a source of close food/nutrients. Since they are nocturnal katydids usually only move about their vegetation habitats in the night time as this allows for the highest chance of safety and food collection.

Species found in Tettigoniidae have a wide variety of foraging methods and diets, such as feeding on dead carcasses or other insects, feeding on pollen, and most commonly, foraging on plants. ''C. simplex'', as well as other species in the subfamily Phaneropterinae, have been observed specifically foraging on plants, but their diet contains a wide variety of such. Primary host plants in New Zealand that have been observed are peach trees, pines, eucalypts, roses, and acacias, and three indigenous species, mahoe, beech trees in the genera ''Nothofagus'', and manuka. Additionally, species in Phaneropterinae have been observed to prefer plants with higher protein content such as flowering species and the flowers themselves, but many are completely capable of developing at a normal rate while only consuming the green leafy matter from plants. While the common garden katydid has the capability to make a sizable impact on gardens, they are not considered an economic threat nor pest.

Katydids and other species in Orthoptera are an important component of many vertebrate diets, such as frogs, lizards, bats, and birds, but the coloration and camouflage that ''C. simplex'' has developed and evolved to have, like many species of katydid, put them at an advantage to predators. In addition to vertebrate predators, insects that have been known to hunt and subdue katydids include tachinid flies , digger wasps , spiders, some species of ants, and many predatory insects that are larger than katydids. Large predatory insects, however, are more of an issue for Australian ''C. simplex'' residents, while New Zealand residents have a tougher time with birds. While the camouflage puts katydids at somewhat of an advantage in some respects for predation, Lysaght describes ''C. simplex'' as a “sluggish insect”, relying primarily on their appearance to stay hidden from predators.
