Further Investigations of Hispaniolan Eumastacoid Grasshoppers (Espagnolinae: Episactidae: Orthoptera)

Immersion Tolerance in Rangeland Grasshoppers (Orthoptera: Acrididae)

The Cytology of Tasmanian Short-Horned Grasshoppers ( Orthoptera: Acridoidea)

Mainly because of their large size, and general suitability for cytological study the chromosomes of the short-horned grasshoppers (superfamily Acridoidea) have been the subject of wide research. In the largest and most widely studied family, the Acrididae, early workers (McClung, 1905; Davis, 1908) reported the male number as being uniformly twentythree rod-shaped chromosomes, but Granata (191...

Host Selection by Grasshoppers (orthoptera: Acrididae) Inhabiting Semi-aquatic Environments

Through laboratory choice tests involving 19 plant species, we assessed the host selection behavior of six grasshopper species: Stenacris vitreipennis (Marschall) (glassywinged toothpick grasshopper), Leptysma marginicollis (Serville) (cattail toothpick grasshopper), Gymnoscirtetes pusillus Scudder (little wingless grasshopper), Paroxya clavuliger (Serville) (olivegreen swamp grasshopper), Paro...

Alternate tactics in male bladder grasshoppers Bullacris membracioides (Orthoptera: Pneumoridae)

Bladder grasshoppers (Orthoptera, Pneumoridae) are a unique group of nocturnal, specialized herbivores, endemic to coastal regions of Southern Africa. Adult males are characterized by an inflated abdomen, which develops at the final molt, and a signaling system capable of producing high intensity calls detectable by conspecifics at distances of up to 2 km. Female response to male calls leads to...

New and little-known pygmy grasshoppers (Orthoptera: Tetrigidae) from Thailand.

An annotated list of 39 species in 25 genera and seven subfamilies of the pygmy grasshoppers (Orthoptera: Tetrididae) from Thailand is given; from these 18 species are recorded from this country for the first time. Five new species are described: Cotysoides gaponi sp. nov. (subfamily Metrodorinae), Eucriotettix anisyutkini sp. nov., Gavialidium bufocrocodil sp. nov., Scelimena bellula sp. nov. ...
