Definition: organs in insects that are involved in the perception of sound; just below the knee in the tibia of all legs in most insects. Reception is performed by aggregations of scolopidia, the unit mechanoreceptor in invertebrates.
Definition: A compound eye with no separation between the crystalline-cone layer and the retinula, each rhabdom receiving light only from its own corneal lens.

Definition: arthropod sensory structures consisting of special sensilla called the scolopidia, which are mechano-transducers and respond mainly to stretch or flexion. In insects, they consist of bundles of internal sensilla, each of which has a cap cell, an enveloping cell and one or more sense cells.
