[Morphology of the antennal sensory cone in insect larvae from various orders]

This article describes the morphology of antennae in larvae of three species of beetles from the families Cerambycidae and Chrysomelidae; one species of the caddis fly from the family Limnephilidae; and four species of dipterans from the families Culicidae, Chironomidae, and Muscidae. In all investigated species, the antenna has a sensory cone on it. Larvae of the caddis fly, longhorn beetles, and leaf beetles have on their antenna solitary sensillae and the sensory cone. This proves the advanced evolution of these species. Despite reduction of the head capsule, the antennal sensory cone in +-9/58 larvae of higher dipterans has become the dominant sensory structure.
