Molecular phylogeny of the scorpionflies Panorpidae (Insecta: Mecoptera) and chromosomal evolution
Cladistics, 2018AbstractPanorpidae is the most species‐rich family in Mecoptera with ca. 470 species in the Northern Hemisphere. However, the intergeneric phylogenetic relationships of Panorpidae remain unsatisfactorily resolved to date. Here, we used molecular and cytogenetic approaches to determine the phylogenetic relationships of Panorpidae in the evolutionary ...

Fine structure of the midgut of Sinopanorpa tincta (Navás) (Mecoptera: Panorpidae)
Tissue and Cell, 2014Fine structure of the midgut and degeneration of the midgut epithelium of the scorpionfly Sinopanorpa tincta (Navás) adults were investigated using light microscopy and scanning and transmission electron microscopy. The results show that the tubular midgut lacks gastric caeca and is composed of an outer longitudinal and an inner circular muscle layer ...

Competition and Coexistence among Panorpa Scorpionflies (Mecoptera: Panorpidae)
Ecological Monographs, 1980The ecological and behavioral interactions of adults of nine species of Panorpa scorpionflies were studied during 1971—1974 at eight woodland sites in southeastern Michigan, USA. The species overlap considerably in habitat use, diurnal foraging time and location, and diet. All species inhabit primarily the herb stratum of moist forests.

Ultrastructure of the seminal vesicle and sperm storage in Panorpidae (Insecta: Mecoptera)
Micron, 2010The histology and ultrastructure of the seminal vesicle, male accessory gland and the epididymis in Panorpa and Sinopanorpa were observed using light microscopy and scanning and transmission electron microscopy. The seminal vesicle consists of a mono-layered elongated columnar epithelium, which contains abundant electron-dense granules and secretory ...

Micron, 2010
Specific genitalic morphology reflects vital sexual functions in insects and examination of genitalic structures is important in understanding copulatory mechanisms. The morphology of male and female genitalia was investigated in the scorpionfly Panorpa jilinensis using light and scanning electron microscopy.

Male Pair-Formation Pheromones in Panorpa Scorpionflies (Mecoptera: Panorpidae)
Environmental Entomology, 1979Female Panorpa responded olfactorily to conspecific males which have everted their genital pouches (i.e., “callings”). Females showed no olfactory response to males whose genital pouch was covered or to non-calling sexually inactive males. Males did not respond olfactorily to “calling” males, to receptive females, or to copulating pairs.
