The evolution of photoreceptor cells and eyes in Metazoa is far from being resolved, although recent developmental and morphological studies provided strong evidence for a common origin of photoreceptor cells and existence of sister cell ty...

The behavioural sequence of the oviposition process can be quite distinct in herbivorous leaf beetles: eggs are either connected to the plant surface or laid into mesophyll tissue. Females of two beetle species were recorded with a digital ...
The organization and evolutionary implications of neuropils and their neurons in the brain of the onychophoran Euperipatoides rowelli [0.03%]

This account describes the organization of the brain of the adult Euperipatoides rowelli, a member of the Onychophora or "velvet worms." The present account identifies three cerebral divisions, the first of which contains primary olfactory ...
Functional division of intrinsic neurons in the mushroom bodies of male Spodoptera littoralis revealed by antibodies against aspartate, taurine, FMRF-amide, Mas-allatotropin and DC0 [0.03%]

The constitutive criterion for the evolutionary successful clade of ecdysozoans is a protective exoskeleton. In insects the exoskeleton, the so-called cuticle consists of three functional layers, the waterproof envelope, the proteinaceous e...

The venom apparatus morphology was examined in 25 species of Cynipoidea, representing 11 parasitoid taxa; 12 gall inducers and two inquilines. Typically the venom apparatus consists of an oval or bilobed reservoir connected to the oviposito...

Bug ovaries are of the telotrophic meroistic type. Nurse cells are restricted to the anterior tropharium and are in syncytial connection with the oocytes via the acellular trophic core region into which cytoplasmic projections of oocytes an...

Pericardial cells are present in a wide variety of insects and are thought to constitute the majority of 'athrocytes (nephrocytes)'. In contrast, peritracheal athrocytes have only been observed in Bombyx mori L. Although peritracheal athroc...
