Spatial Vision in Band-Winged Grasshoppers (Orthoptera: Acrididae: Oedipodinae)
Spatial vision in band-winged grasshoppers (Orthoptera: Acrididae: Oedipodinae) A Senior Thesis Presented to the Faculty of the Department of Organismal Biology and Ecology, Colorado College By Alexander B. Duncan Bachelor of Arts Degree in Organismal Biology and Ecology May, 2017 Approved by: _________________________________________ Dr. Nicholas Brandley Primary Thesis Advisor ________________________________________ Dr. Emilie Gray Secondary Thesis Advisor ABSTRACT Visual acuity, the ability to resolve fine spatial details, can vary dramatically between and within insect species. Body-size, sex, behavior, and ecological niche are all factors that may influence an insect’s acuity. Band-winged grasshoppers (Oedipodinae) are a subfamily of grasshoppers characterized by their colorfully patterned hindwings. Although researchers have anecdotally suggested that this color pattern may attract mates, few studies have examined the visual acuity of these animals, and none have examined its implications on intraspecific signaling. Here, we compare the visual acuity of three bandwing species: Dissosteira carolina, Arphia pseudonietana, and Spharagemon equale. To measure acuity in these species we used a modified radius of curvature estimation (RCE) technique. Visual acuity was significantly coarser 1) in males compared to females, 2) parallel to the horizon compared to the perpendicular, and 3) in S. equale compared to other bandwings. Unlike many insect families, body size within a species did not correlate with visual acuity. To examine the functional implications of these results, we modeled the appearance of different bandwing patterns to conspecifics. These results suggest that hind- wing patterning could only be used as a signal to conspecifics at short distances (<50cm). This study furthers the exploration of behavior and the evolution of visual systems in bandwings. -
Invertebrate Distribution and Diversity Assessment at the U. S. Army Pinon Canyon Maneuver Site a Report to the U
Invertebrate Distribution and Diversity Assessment at the U. S. Army Pinon Canyon Maneuver Site A report to the U. S. Army and U. S. Fish and Wildlife Service G. J. Michels, Jr., J. L. Newton, H. L. Lindon, and J. A. Brazille Texas AgriLife Research 2301 Experiment Station Road Bushland, TX 79012 2008 Report Introductory Notes The invertebrate survey in 2008 presented an interesting challenge. Extremely dry conditions prevailed throughout most of the adult activity period for the invertebrates and grass fires occurred several times throughout the summer. By visual assessment, plant resources were scarce compared to last year, with few green plants and almost no flowering plants. Eight habitats and nine sites continued to be sampled in 2008. The Ponderosa pine/ yellow indiangrass site was removed from the study after the low numbers of species and individuals collected there in 2007. All other sites from the 2007 survey were included in the 2008 survey. We also discontinued the collection of Coccinellidae in the 2008 survey, as only 98 individuals from four species were collected in 2007. Pitfall and malaise trapping were continued in the same way as the 2007 survey. Sweep net sampling was discontinued to allow time for Asilidae and Orthoptera timed surveys consisting of direct collection of individuals with a net. These surveys were conducted in the same way as the time constrained butterfly (Papilionidea and Hesperoidea) surveys, with 15-minute intervals for each taxanomic group. This was sucessful when individuals were present, but the dry summer made it difficult to assess the utility of these techniques because of overall low abundance of insects. -

The geographical distribution of M. bowditchi is very similar to the range of its host plants and its feeding association varies in relation to sagebrush dis- tribution. Melanoplus bowditchi bowditchi Scudder and M. bowditchi canus Hebard were described based on their feeding association with diVerent sagebrush species, sand sagebrush and silver sagebrush, respectively. Recently, M. bowditchi have been observed feeding on other plant species in western Nebraska. We collected adult M. bowditchi feeding on four plant species, sand sagebrush, Artemisia filifolia, big sagebrush, A. tridentata, fringed sagebrush, A. frigidus, and winterfat, Kraschenin- Submitted 10 January 2014 nikovia lanata.

Here we examine the visual acuity of three species of sexually 15 dimorphic band-winged grasshoppers, in which females are the larger sex (Arphia 16 pseudonietana, Dissosteira carolina, and Spharagemon equale; total n = 98). Using a radius of 17 curvature estimation method, we find that females have ~21% finer vision in the most acute 18 region and axis of the eye than do males. Further explorations of the eyes of the species 19 showing the greatest size dimorphism (D. carolina) suggest that this VA dimorphism is driven by 20 females having larger eyes with more ommatidia. -
Arizona Wildlife Notebook
ARIZONA WILDLIFE CONSERVATION ARIZONA WILDLIFE NOTEBOOK GARRY ROGERS Praise for Arizona Wildlife Notebook “Arizona Wildlife Notebook” by Garry Rogers is a comprehensive checklist of wildlife species existing in the State of Arizona. This notebook provides a brief description for each of eleven (11) groups of wildlife, conservation status of all extant species within that group in Arizona, alphabetical listing of species by common name, scientific names, and room for notes. “The Notebook is a statewide checklist, intended for use by wildlife watchers all over the state. As various individuals keep track of their personal observations of wildlife in their specific locality, the result will be a more selective checklist specific to that locale. Such information would be vitally useful to the State Wildlife Conservation Department, as well as to other local agencies and private wildlife watching groups. “This is a very well-documented snapshot of the status of wildlife species – from bugs to bats – in the State of Arizona. Much of it should be relevant to neighboring states, as well, with a bit of fine-tuning to accommodate additions and deletions to the list. “As a retired Wildlife Biologist, I have to say Rogers’ book is perhaps the simplest to understand, yet most comprehensive in terms of factual information, that I have ever had occasion to peruse. This book should become the default checklist for Arizona’s various state, federal and local conservation agencies, and the basis for developing accurate local inventories by private enthusiasts as well as public agencies. "Arizona Wildlife Notebook" provides a superb starting point for neighboring states who may wish to emulate Garry Rogers’ excellent handiwork. -

Many species are phytophagous, feeding directly on plants; filling the primary consumer role of moving energy stored in plants to organisms that are unable to digest plant material (Triplehorn and Johnson 2005). Insects are responsible for a majority of the pollination that occurs and pollination relationships between host plant and pollinator can be very general with one pollinator pollinating many species of plant or very specific with both the plant and the pollinator dependant on each other for survival (Triplehorn and Johnson 2005). Insects can be mutualist, commensal, parasitic or predatory to the benefit or detriment -
Field Guide to Some of the Common Grasshoppers of the Front Range of Colorado
Field guide to some of the common grasshoppers of the Front Range of Colorado Instructions: The following guide presents the grasshopper species most commonly found along an elevational gradient from the plains of Boulder, Colorado, to the subalpine that lies to the west. Use this guide to identify the species that are found during each weekly sample at your designated site. This will help you determine whether climate change is impacting the timing to adulthood of each community. Grasshoppers of the Front Range There are 548 species of North American grasshoppers and 133 of these occur in Colorado. Only about a dozen of these species are considered important pests on rangelands, with five of these causing most problems on crops. Within the Front Range of Colorado, 72 species can be found, although most are relatively uncommon. The most commonly encountered species along our lower foothills (1752m) to subalpine (3000 m) transect can be placed into 3 groups (subfamilies); Gomphocerinae, Melanoplinae and Oedipodinae. The Gomphocerinae (slant-faced grasshoppers) are grass specialists that tend to be small and are the grasshoppers commonly heard in meadows chorusing during the day. The Melanoplinae (spur-throated grasshoppers) are the most commonly encountered grasshoppers and are primarily forb feeders. Melanoplinae are small (but some can be large) and several of these species tend to be short winged and cannot actively fly, They do not chorus. Most of the Oedipodinae (banded-winged grasshoppers) tend to be grass feeders or herbivorous (both grass and forb feeding) and are rarely solely forb feeders. These grasshoppers are commonly found in open areas where they bask and display, they vary considerably in size, and are all active fliers that often use their wings to make loud clicking sounds. -
A List of the Orthoptera of Ohio
Mar., 1904.] A List of the Orthoptera of Ohio. 109- A LIST OF THE ORTHOPTERA OF OHIO.* CHARGES S. MEAD. A little over a year ago the writer, at the suggestion of Prof. Herbert Osborn, began to work over the Orthoptera in the Entomological collection at the Ohio State University, with a view of eventually publishing a list of those found in Ohio. During the spring and fall, collecting was done in central Ohio and during the summer in northern Ohio, mostly in the neighborhood of Sandusky. Heretofore, very little work has been done on the grasshoppers of Ohio and nothing published. Very few references are found in the literature to Orthoptera collected in this state. The Orthoptera, in general, reach their adult condition in late summer and early fall, only a few species maturing and dying before the first of August. Some of the species listed below are fairly common in parts of Ohio and others are quite scarce. Syrbula admirabilis (Uhler). This is a southern form with its northern range about the center af Ohio. On September 23 three females were captured at Buckeye Lake. Orphulella speciosa (Scudder). Blatchley reports having captured but a single pair in Indiana, where it is quite scarce. Morse writes of its being common in the New England states. It is fairly plentiful in the vicinity of Columbus and Sandusky. Hippiscus rugosus (Scudder). On September 23, a coral winged form of this species was captured at Buckeye L,ake. It agrees with the descriptions of '' rugosus'' in all particulars except the color of the wings, which are usually lemon or orange. -
