The complex tibial organ of the New Zealand ground weta: sensory adaptations for vibrational signal detection [PDF]

open access: yes, 2017
In orthopteran insects, a complex tibial organ has evolved to detect substrate vibrations and/or airborne sound. Species of New Zealand weta (Anostostomatidae) with tympanal ears on the foreleg tibia use this organ to communicate by sound, while in ...

Modelling the distribution of the invasive Roesel’s bushcricket (Metrioptera roeselii) in a fragmented landscape [PDF]

open access: yes, 2011
The development of conservation strategies to mitigate the impact of invasive species requires knowledge of the species ecology and distribution. This is, however, often lacking as collecting biological data may be both time-consuming and resource ...

Different steps in the evolution of neo-sex chromosomes in two East African Spalacomimus species (Orthoptera: Tettigoniidae: Hetrodinae)

open access: yesEuropean Journal of Entomology, 2015
Two orthopteran species belonging to the East African genus Spalacomimus, S. verruciferus and S. talpa (Tettigoniidae: Hetrodinae), were investigated using both molecular cytogenetic techniques, including fluorescence in situ hybridization with 18S rDNA ...

New Orthopteroid Records in Michigan Derived from Sampling a Small Field [PDF]

open access: yes, 2017
(excerpt) A 1.8 acre sandy field in Isabella County, Michigan was sampled in 1971 and 1972 to obtain data on ecological and chronological distribution of orthopteroid species (Bland and Swayze 1973a,b).

Does wing dimorphism affect mobility in Metrioptera roeselii (Orthoptera: Tettigoniidae)?

open access: yesEuropean Journal of Entomology, 2011
Range shifts are among the most conspicuous effects of global warming. Marked changes in distribution are recorded both for highly mobile species of insects, which are capable of flight, and wing-dimorphic species with predominantly short-winged ...

The Auditory System of the Dipteran Parasitoid Emblemasoma auditrix (Sarcophagidae) [PDF]

open access: yes, 2016
Several taxa of insects evolved a tympanate ear at different body positions, whereby the ear is composed of common parts: a scolopidial sense organ, a tracheal air space, and a tympanal membrane. Here, we analyzed the anatomy and physiology of the ear at

What determines the number of auditory sensilla in the tympanal hearing organs of Tettigoniidae? Perspectives from comparative neuroanatomy and evolutionary forces [PDF]

open access: yesJournal of Orthoptera Research, 2019
Insects have evolved complex receptor organs for the major sensory modalities. For the sense of hearing, the tympanal organ of Tettigoniidae (bush crickets or katydids) shows remarkable convergence to vertebrate hearing by impedance conversion and ...

Notes on Feeding Behavior of Atlanticus Testaceus (Orthoptera: Tettigoniidae) [PDF]

open access: yes, 2017
The Biology and Feeding behavior of Atlanticus testaceus (scudder) has received considerable attention by Gangwere (1966, 1967). While studying summer feeding of the adult Atlanticus testaceus in a Northern Michigan Jack Pine forest on the seeds of ...
