Abstract

Abstract:

The ultrastructures of the attachment apparatus of 51 insect species from 7 orders were examined with scanning electron microscopy (SEM). Three types of adhesive structure, the smooth structure, the hairy structure, and the sucker, were found and are described in this paper. Based on the morphology and the distribution of the adhesive structures, the smooth adhesive structures can be subdivided into three types: the smooth arolium, the smooth pulvilli, and the smooth euplantulae; the hairy adhesive structures can be subdivided into four types: the hairy adhesive soles, the hairy pulvilli, the fossula spongiosa, and the adhesive structure transformed from the tarsal thorns; and the sucker is a specific adhesive structure found in the species of Dytiscidae. This study shows that the structures of the attachment apparatus are very diverse in insects and are very distinct at the order level. These facts can be used for taxonomic identifications and phylogenetic studies.

Key words: adhesion, ultrastructure, smooth, hairy
