[Structure of the mushroom bodies in Scarabaeoidea (Coleoptera): II. Phytophagous Scarabaeidae and general discussion].
The mushroom body structure is progressively more complicated within the superfamily Scarabaeoidea. In the basal families and coprophagous Scarabaeidae, the calyx region is asymmetrical and poorly developed but reaches the maximal degree of development in the phytophagous Scarabaeidae of the subfamilies Melolonthinae and Cetoniinae. These Scarabaeidae have two separate calyces; moreover, some species have additional regions of glomerular neuropile. The processes of different Kenyon cell types segregate into special subdivisions of vertical and medial lobes. It is assumed that a progressive development of the mushroom body in phytophagous Scarabaeidae is associated with the need to integrate olfactory and visual information.
