Morphology and function of the ovipositor mechanism in Ceraphronoidea (Hymenoptera, Apocrita)

open access: yesJournal of Hymenoptera Research, 2013
The ovipositor of apocritan Hymenoptera is an invaluable source of phylogenetically relevant characters, and our understanding of its functional morphology stands to enlighten us about parasitoid life history strategies. Although Ceraphronoidea is one of

\u3ci\u3eSaga Pedo\u3c/i\u3e (Pallas) (Tettigoniidae: Saginae), an Old World Katydid, New to Michigan [PDF]

open access: yes, 2017
At least four species of Old World Tettigoniidae are known to have been introduced into, and to have become established in the United States. One of these, Phaneroptera quadripunctata Brunner was first taken at Niles, California in 1932 and was reported ...

Morphology of exophytic ovipositors in dragonflies (Odonata: Gomphidae, Corduliidae, Libellulidae), with particular reference to ovipositor muscles and sensilla

open access: yesInternational Journal of Odonatology, 2011
A comparative study of female external genitalia was carried out in representatives of three dragonfly families that lay eggs exophytically, with special emphasis placed on skeletal musculature and sensilla. Female external genitalia are characteristically represented by the vulvar lamina and rudiments on the 9th sternum.

Evolutionary Systematics of Two Co‐Occurring Paludomid Freshwater Gastropods in Thailand (Cerithioidea: Paludomidae)

open access: yesZoologica Scripta, Volume 55, Issue 2, Page 244-272, March 2026.
ABSTRACT Paludomidae is a diverse family of limnic gastropods in the Cerithioidea, with a distribution range including most of tropical sub‐Saharan Africa, the Nile Valley, Madagascar, the Seychelles, as well as South and Southeast Asia. Its systematics and taxonomy are currently in a state of confusion, with Thailand being inhabited by probably two ...

Morphological characteristics of sensilla on the female ovipositor of Lype phaeopa (Psychomyiidae; Trichoptera)

open access: yesJournal of Insect Science, 2003
An important aspect of the association of Lype phaeopa (Stephens) with submerged wood is the oviposition behavior of adult females, which preferably oviposit their eggs on moist emergent or submerged parts of woody debris with a structured surface.

First records of Acrotaphus fuscipennis (Cresson) and of A. tibialis (Cameron) from the United States (Hymenoptera: Ichneumonidae) [PDF]

open access: yes, 2005
Acrotaphus fuscipennis (Cresson), distinctive because of its black wings and bright red body, is recorded for the first time from the United States. It was reared from araneid spiders collected in Florida, which constitutes the first host record for this

Drosophila species (Diptera: Drosophilidae) oviposition patterns on fungi: The effect of allospecifics, substrate toughness, ovipositor structure and degree of specialisation

open access: yesEuropean Journal of Entomology, 2003
To determine if small-scale resource partitioning aids coexistence in fungal breeding Diptera we investigated the avoidance of interspecific larval competition by micro-resource partitioning of the host substrate in several species of Drosophila ...
