leaf-rolling grasshopper, any of a group of insects in the subfamily Gryllacridinae (order Orthoptera) that are wingless or nearly wingless, have long cerci and antennae, and appear somewhat humpbacked. The leaf-rolling grasshoppers are closely related to raspy crickets, which are also in subfamily Gryllacridinae. The California leaf roller (Camptonotus carolinensis), about 15 mm (0.5 inch) long, is active at night, as are other members of this subfamily. The leaf-rolling grasshopper spends the day in a leaf that it rolls and ties with silk; at night the insect emerges and feeds on aphids. It has no sound-producing or hearing organs.

leaf-rolling weevil, (family Attelabidae), any member of a subgroup of the weevil family, Curculionidae (insect order Coleoptera) whose females protect newly laid eggs by rolling them up inside a growing leaf. After hatching, the larvae eat the leaf from within. Adults are generally small (3–6 mm [0.12 to 0.24 inch]) and black, red, or black and red. Adults are free-living but associated with certain tree species. Attelabus nitens, for example, is associated with oak, and Rhynchites populi with poplar. Two species of leaf-rolling weevils lay their eggs in hazel trees: R. betuleti, which rolls the whole leaf, and Apoderus coryli, which rolls only one side of the leaf.
