Adaptive Female-Mimicking Behavior in a Scorpionfly

Science, 1979
This study provides a clear example of female-mimicking behavior by males in insects and evaluates quantitatively the adaptive significance of this behavior, which is poorly understood in many other organisms. Males of Hylobittacus apicalis provide females with a prey arthropod during copulation.

The role of male's anal horns in copulation of a scorpionfly

Journal of Zoology, 2014
AbstractSexual conflict drives evolution of sexually antagonistic adaptations that give advantages to the bearer. As a consequence of sexual conflict, male scorpionflies (Mecoptera: Panorpidae) provide nuptial gifts for the female and use grasping organs to repress female resistance.

The Larval Eye of Nannochoristid Scorpionflies (Insecta, Mecoptera)

Acta Zoologica, 1994
Abstract The stemmata of last–instar Nannochoristalarvae are compound eyes composed of 10 or more ommatidia. Each ommatidium has four Semper cells, four distal and four proximal retinula cells which form a cruciform and layered rhabdom. The ommatidia are separated by epidermal cells (possibly rudimentary pigment cells). Corneal lenses are lacking.

Revision of the bizarre Mesozoic scorpionflies in the Pseudopolycentropodidae (Mecopteroidea)

Insect Systematics & Evolution, 2005
AbstractThe Mesozoic family Pseudopolycentropodidae presently consists of seven described species from the mid-Triassic to the Late Jurassic of Europe and Asia. Pseudopolycentropus prolatipennis Whalley, from the Early Jurassic of England, is revised based on re-examination of the type.

Scorpionflies as kleptoparasites of web-building spiders

Nature, 1975
ONLY a few species of spiders and insects are known regularly to inhabit spider webs. Known associations involve predation or commensalism. Spiders of the family Mimetidae invade the webs of other spiders to devour the owner of the web. Small spiders of the genus Argyrodes (Theridiidae) are often seen in the webs of larger spiders, where they seem to ...

Functional morphology of the mouthparts in the scorpionfly Sinopanorpa tincta (Mecoptera: Panorpidae)

Micron, 2011
The feeding mechanism of insects can be deduced from the morphology of their mouthparts. The mouthpart morphology of the scorpionfly Sinopanorpa tincta (Navás) was investigated using light and scanning electron microscopy. The mandibulate mouthparts of S.

Global biodiversity of Scorpionflies and Hangingflies (Mecoptera) in freshwater

Hydrobiologia, 2007
Seven species and one sub-species of Mecoptera are aquatic as larvae and pupae. All aquatic species are classified in two genera of the family Nannochoristidae and have very restricted geographic ranges, with three species confined to extreme southern South America, three species and one sub-species confined to New South Wales or Tasmania in Australia,

Pape in Panorpa scorpionflies and a general rape hypothesis

Animal Behaviour, 1980
Abstract The adaptive significance of heterosexual rape is difficult to demonstrate because (1) female coyness is difficult to distinguish from apparent rape, and (2) male fitness must be enhanced by rape. Male Panorpa scorpionflies inseminate unwilling females by securing the female's wings in an abdominal clamp.
