The Carolina Leaf-roller (Camptonotus carolinensis) is the only representative of the family of Leaf-rolling crickets. It is active at night, preying on aphids. It likes to build a daytime retreat for itself by rolling leaves and securing them with silk threads spun from glands in its mouth.
As opposed to all other crickets the Leaf-rolling crickets don’t jump.
When disturbed, the cricket inflates its abdomen and raises itself with some of the legs up right. It then repeatedly moves the abdomen against the legs creating a low, raspy sound. That’s why these insects are sometimes also called ‘raspy crickets’. At the same time it makes noise with the mandibles and wings. If this cannot drive away the dangers, the activity becomes more vigorous. The raspy sound seems to serve a defensive purpose only, as the cricket, both male and female, seems do not have any hearing organ. Many other crickets do (mostly in the front legs).
