Siliquofera grandis, the Giant Hooded Katydid, is one of the largest bush crickets in the world and a true rainforest specialist. Native to the canopies of Papua New Guinea and nearby Indonesian islands, this species is instantly recognisable by its immense size—adults reach 10–13 cm in body length with wingspans of up to 27 cm—and by the distinctive hood-like pronotum that covers part of its abdomen. Its vivid green coloration and leaf-like wings provide excellent camouflage among foliage, allowing it to blend seamlessly into its environment.
In the wild, S. grandis lives high in the rainforest canopy, feeding exclusively on leaves and other plant matter. It is strictly herbivorous, browsing on a wide range of vegetation including bramble, raspberry, oak, hazel, fig, and rose leaves. In captivity, it readily accepts fruits and vegetables such as apple, cucumber, carrot, and lettuce, making it relatively easy to maintain compared to more specialised species. Its strong mandibles allow it to chew through tough foliage, and its nocturnal habits mean most feeding occurs at night.
 
Reproduction is equally impressive: females can lay hundreds of eggs, each buried in soil using their ovipositor. Eggs hatch after several months into wingless nymphs that resemble stubby versions of the adults, gradually molting into their full form. Adults can live for over a year, making them one of the longer-lived orthopterans kept in captivity. Their combination of size, longevity, and striking appearance has made them a favourite among insect enthusiasts worldwide.
