Adapting the Dragonfly Biotic Index to a katydid (Tettigoniidae) rapid assessment technique: case study of a biodiversity hotspot, the Cape Floristic Region, South Africa [PDF]

open access: yesJournal of Orthoptera Research, 2017
Global biodiversity faces many challenges, with the conservation of invertebrates among these. South Africa is megadiverse and has three global biodiversity hotspots. The country also employs two invertebrate-based rapid assessment techniques to evaluate

Versatile aggressive mimicry of cicadas by an Australian predatory katydid.

open access: yesPLoS ONE, 2009
BackgroundIn aggressive mimicry, a predator or parasite imitates a signal of another species in order to exploit the recipient of the signal. Some of the most remarkable examples of aggressive mimicry involve exploitation of a complex signal-response ...

Overlooked flower-visiting Orthoptera in Southeast Asia [PDF]

open access: yesJournal of Orthoptera Research, 2017
The study of insect–plant interactions such as flower visitors, pollinators, and florivores, are important for understanding the natural world. However, not all flower-visiting insects are equally well known, especially in the biodiverse Southeast Asian ...

From Understory to Canopy: In situ Behavior of Neotropical Forest Katydids in Response to Bat Echolocation Calls

open access: yesFrontiers in Ecology and Evolution, 2018
Predator-prey interactions take place in complex environments, and research on the sensory ecology of predator-detection relies on understanding when, where, and how prey experience and respond to predator cues.

Going silent? Evidence for independent losses of acoustic communication in tree crickets (Insecta, Orthoptera, Grylloidea, Oecanthidae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...

Dietary habits of the Hairy Big-eared Bat (Phyllostomidae, Micronycteris hirsuta) based on insect remains at a roost site

open access: yesACI Avances en Ciencias e Ingenierías, 2012
Hairy Big-eared Bats, Micronycteris hirsuta, have been observed to occupy attics in buildings that are not well sealed. Stereotypically, prey is brought to the roosting site for consumption where wings and hard structures are discarded while soft body ...

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

open access: yesPlant Biology, EarlyView.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

The Sertão Leaf Katydid – a new genus of Pterochrozinae Walker, 1870 (Insecta, Orthoptera) from the Caatinga in Northeastern Brazil

open access: yesEuropean Journal of Taxonomy
Pterochrozinae are katydids endemic to the Neotropics, commonly known as peacock or leaf katydids. Several areas in the Neotropical are poorly sampled for leaf katydids, and there are few experts working with this group. Most of Pterochrozinae diversity

The scolopidial accessory organ in Gonatoxia bush-crickets (Tettigonioidea, Phaneropterinae, Holochlorini) [PDF]

open access: yesJournal of Orthoptera Research
The scolopidial accessory organ is a relatively small and compact chordotonal organ consisting of mechanosensory scolopidial sensilla. The accessory organ is placed in the tibia next to the larger subgenual organ in several Orthoptera.
