The grasshopper antenna is an articulated appendage associated with the deutocerebral segment of the head. In the early embryo, the meristal annuli of the antenna represent segment borders and are also the site of differentiation of pioneer...
Spermatozoa and spermiogenesis of Liphistius cf. phuketensis (Mesothelae, Araneae, Arachnida) with notes on phylogenetic implications [0.03%]

Izabela Jedrzejowska
Previtellogenic oocytes of a common cellar spider, Pholcus phalangioides, contain a single aggregation of organelles referred here to as the Balbiani body. It is a well defined ooplasmic structure predominantly composed of fine granular nua...
Morphology of testicular and post-testicular spermatozoa in Microstigmus arlei Richards, 1972 and M. nigrophthalmus Melo, 1992 (Hymenoptera: Apoidea: Pemphredoninae) with phylogenetic consideration [0.03%]
理查兹蜂腰泥蜂属Microstigmus两种物种的精子形态学及其系统发育意义研究（蜜蜂总科）
Uyrá Zama,Jane Moreira,Sônia Nair Báo et al.
Uyrá Zama et al.
The sperm of Microstigmus arlei and Microstigmus nigrophthalmus are twisted in a spiral and consist of two regions: the head, formed by an acrosome and a nucleus, and the flagellum, formed by two asymmetric mitochondrial derivatives, a long...
The analysis of the mechanosensory origin of the infrared sensilla in Melanophila acuminata (Coeloptera; Buprestidae) adduces new insight into the transduction mechanism [0.03%]
拟步甲科急枪甲属昆虫红外感觉器的机械感受起源分析为该类红外感觉的信号转导机制提供了新视角

Anke Schmitz
The thoracic infrared (IR) sensilla of the pyrophilous jewel beetle Melanophila acuminata most likely have evolved from hair mechanoreceptors (sensilla trichodea). To further elucidate the sensory transduction mechanism, the morphology of I...
Diversity in structural ultraviolet coloration among female sulphur butterflies (Coliadinae, Pieridae) [0.03%]
硫黄蝶亚族雌性紫外线颜色信号的多样性研究
Ronald L Rutowski,Joseph M Macedonia,Darrell J Kemp et al.
Ronald L Rutowski et al.
In some species of sulphur butterflies (Pieridae: Coliadinae) females as well as males display bright structural reflectance on their dorsal wing surfaces, although comparatively little attention has been paid to this coloration in females....
Homology of the wing base sclerites in Ephemeroptera (Insecta: Pterygota) - a reply to Willkommen and Hörnschemeyer [0.03%]
蜉蝣目昆虫翅基节类器官的同源性——回应Willkommen和Hörnschemeyer教授的观点论文

Joop C van Lenteren et al.
Location, structure and histology of chemosensilla on the tip of the ovipositor of the parasitoid Leptopilina heterotoma are described based on SEM and TEM studies. Furthermore, we developed a method for recording extracellular action poten...
The homology of wing base sclerites and flight muscles in Ephemeroptera and Neoptera and the morphology of the pterothorax of Habroleptoides confusa (Insecta: Ephemeroptera: Leptophlebiidae) [0.03%]
