black-legged meadow katydid Orchelimum nigripes Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Orthoptera Family: Tettigoniidae ILLINOIS STATUS common, native FEATURES Katydids have feet with four segments. The body generally resembles that of grasshoppers, but katydids have long, threadlike antennae instead of the grasshoppers’ short antennae. The black- legged meadow katydid is about one inch long. Its body is green with a blue tinge. There is yellow on the femur of the first two pairs of legs, and the tibias are black. The head is white- brown and has red eyes. The female’s ovipositor is curved. BEHAVIORS The lifespan of a katydid is about a year. Females usually lay their eggs at the end of summer in plant stems. The eggs are typically oval and laid in rows on the plant. Most katydids overwinter in the egg form. The males have sound-producing organs on their front wings. They use this sound for courtship. During courtship there often is antennal contact between male and female. Katydids are eaten by birds and mammals and may be the target of insect predators and parasites including horsehair worms, wasps and flies. The black-legged meadow katydid sings from July through November. It is generally a species that lives near water, but it may move into dry meadows and thickets. It sometimes sings from trees.

The Evolution of Complex Calls in Meadow
THE EVOLUTION OF COMPLEX CALLS IN MEADOW KATYDIDS _______________________________________ A Dissertation presented to the Faculty of the Graduate School at the University of Missouri-Columbia _______________________________________________________ In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy _____________________________________________________ by NATHAN HARNESS Dr. Johannes Schul, Dissertation Supervisor July 2018 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled THE EVOLUTION OF COMPLEX CALLS IN MEADOW KATYDIDS presented by Nathan Harness, a candidate for the degree of doctor of philosophy, and hereby certify that, in their opinion, it is worthy of acceptance. Professor Johannes Schul Professor Sarah Bush Professor Lori Eggert Professor Patricia Friedrichsen For my family Rachel and Mayr have given me so much. They show me unselfish affection, endless support, and generosity that seems to only grow. Without them the work here, and the adventure we’ve all three gone on surrounding it, would not have been possible. They have sacrificed birthdays, anniversaries, holidays, and countless weekends and evenings. They’ve happily seen me off to weeks of field work and conference visits. I am thankful to them for being so generous, and completely lacking in resentment at all the things that pull their husband and dad in so many directions. They have both necessarily become adept at melting away anxiety; I will forever be indebted to the hugs of a two-year-old and the kind words of his mom. Rachel and Mayr both deserve far more recognition than is possible here. I also want to thank my parents and brother and sisters.

K. Lechner2 The Great Black Wasp, Sphex pensylvanicus Linnaeus, 1763 is a known predator of katydids (Orthoptera: Tettigoniidae) and is rather catholic in its choice of prey seemingly taking any katydid species available. In a previous paper (Lechner 2016), I stated that five species placed in four genera of katydids have been reported as prey items of S. pensylvanicus. Also, I reported four confirmed katydid species that I took from S. pensylvanicus that nest in the soil behind a vertical retaining wall on my residential property in Sioux City, Iowa. Herein, I add the Gladiator Meadow Katydid, Orchelimum gladiator Bruner, 1891 (Figures 1 and 2, next page), to the prey record of S. pensylvanicus. I took this paralyzed katydid from its captor female S. pensylvanicus on 28 August 2017. At that time, the wasp was attempting to enter her nest with her prey item in the north lot line retaining wall. Acknowledgments Many thanks to Dr. Thomas J. Walker (University of Florida, Gainesville, Florida, USA) for identifying the specimen of Orchcelimum gladiator. This katydid was donated to the Ensiferan Collection at the University of Florida.

MARSHALL1 1School of Environmental Sciences, University of Guelph, Guelph, Ontario, Canada N1G 2W1 email, [email protected] Abstract J. ent. Soc. Ont. 145: 61–76 The following seven orthopteroid taxa are recorded from Canada for the first time: Anaxipha species 1, Cyrtoxipha gundlachi Saussure, Chloroscirtus forcipatus (Brunner von Wattenwyl), Neoconocephalus exiliscanorus (Davis), Camptonotus carolinensis (Gerstaeker), Scapteriscus borellii Linnaeus, and Melanoplus punctulatus griseus (Thomas). One further species, Neoconocephalus retusus (Scudder) is recorded from Ontario for the first time. An updated checklist of the orthopteroids of Ontario is provided, along with notes on changes in nomenclature. Published December 2014 Introduction Vickery and Kevan (1985) and Vickery and Scudder (1987) reviewed and listed the orthopteroid species known from Canada and Alaska, including 141 species from Ontario. A further 15 species have been recorded from Ontario since then (Skevington et al. 2001, Marshall et al. 2004, Paiero et al. 2010) and we here add another eight species or subspecies, of which seven are also new Canadian records. Notes on several significant provincial range extensions also are given, including two species originally recorded from Ontario on bugguide.net. Voucher specimens examined here are deposited in the University of Guelph Insect Collection (DEBU), unless otherwise noted.

Integrating Species Distribution Models, Genetics and Morphology to Infer Species Dynamics of New Zealand Phaulacridium Grasshoppers

The thesis may not be reproduced elsewhere without the permission of the Author. Integrating species distribution models, genetics and morphology to infer species dynamics of New Zealand Phaulacridium grasshoppers A thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology Massey University Palmerston North, New Zealand Louisa Maree Sivyer 2016 Abstract Species comparison studies have used a number of different methods that can contribute to our understanding of processes that influence the differences and similarities observed between species. This thesis describes the geographic distribution, spatial genetics, and morphology of two New Zealand Phaulacridium grasshoppers, the widespread P. marginale and the restricted P. otagoense. The primary focus was on Phaulacridium populations from the region of the southern South Island where the two species ranges overlap, for the purpose of examining the evolutionary and ecological interactions of the species. The geographic distribution of the two species was analysed using the recorded and potential modern distribution of Phaulacridium grasshoppers. Models of environmental envelopes for each species demonstrated that the potential distribution of P. marginale covered the majority of New Zealand. In contrast, the potential distribution of P. otagoense is restricted to patches of land primarily in the southern South Island where this species is known to occur. The phylogeographic structure of Phaulacridium species was analysed using dense population samples. Two main mtDNA COI sequence groups were found, one was shallow but geographically widespread, while the other was more diverse but geographically restricted.

In the fifty years since their paper, several factors have combined to increase by nearly one-third the number of orthopterous and dermapterous taxa known for the state. These have been better understanding of the taxonomy of some groups, more extensive collecting, the establishment over the past several years of five advents, and the unquestioned northerly extension during the past two or three decades of the ranges of several species previously known to occur to the south in Ohio and Indiana.
