Dark brown bands on the thorax and abdomen. Adult 9 - 17 mm ● Elongated body with thorax narrower than head and abdomen. ● Yellowish-orange in color. ● Two to three black stripes on the elytra. ● Two black stripes on the head. ● Two black stripes on the thorax. ● Hindwings transparent. Pupa (if ● White in color but darkens during development. applicable) ● Similar in appearance to the adult form, but wings and legs held tightly to the body. Type of feeder (Chewing, sucking, etc.): Chewing Host/s: Adults feed on a variety of plants including bean, beet, carrot, cabbage, corn, eggplant, melon, mustard, pea, pepper, potato, radish, spinach, squash, sweet potato, tomato, clover, soybean, and pigweed. Larvae feed on grasshopper eggs. Description of Damage (larvae and adults): Striped blister beetles damage the leaves of many common crops by defoliation, especially in aggregations. This species has been implicated in the transmission of bean pod mottle virus in soybean which leads to yellow mottling in upper leaves and yield loss. Contamination of cantharidin on plants consumed or touched by animals can lead to blistering. References: Agafitei, N., & Selander, R. (1980).

Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

Grasshopper: Munching Pest Or Controlling Invasives?
Grasshopper: Munching Pest or Controlling Invasives? By Ann M. Mason, Fairfax Master Gardener Intern In my youth I often heard the tale of ‘Jiminy Cricket’ but not much about ‘Gregory Grasshopper.’ While both crickets, grasshoppers and their locust cousins belong to the Orthoptera order, they belong to different suborders and have different characteristics. Crickets and katydids belong to the suborder, Ensifera, with slender antennae longer than their bodies; grasshoppers and locusts belong to the suborder, Wikipedia Commons Wikipedia Caelifera, distinguished by short, horned antennae. Locusts are a grasshopper species, who for a variety of photo: photo: reasons have left their normal solitary life to enter the Red-legged grasshopper swarming phase sometimes caused by drought conditions and followed by robust and rapid vegetative growth. Let’s look at the physical and behavioral characteristics that set crickets and grasshoppers apart and make identification of these insect cousins easier. Grasshoppers are diurnal and active during the day, while crickets are nocturnal, active at night. Generally, grasshoppers are larger than crickets. They are lighter in color than crickets and are neutral green, grey or light brown. Crickets have bright or dark colors. Both grasshoppers and crickets can jump, and grasshoppers can also fly. Antennae size and shape are very different for grasshoppers and crickets. Grasshoppers have short, horn- like antennae, while crickets boast longer, slender ones — longer than their body length. Grasshoppers eat plants (herbivorous); crickets are predators and eat plants and other insects (omnivorous). Both male and female grasshoppers produce chirping sounds by rubbing their hind legs with their wings; only male crickets make a chirping sound by rubbing the top of one wing across the teeth at the bottom of the other wing.

Blister Beetles: Reducing the Risk of Blister Beetle Contamination in Alfalfa Hay
Blister Beetles: Reducing the Risk of Blister Beetle Contamination in Alfalfa Hay. Allen Knutson Extension Entomologist, Texas AgriLife Research and Extension Center, Dallas Blister beetles contain a chemical, cantharidin, that when consumed by horses and other livestock, can cause illness and sometimes death. Blister beetles in alfalfa fields at harvest can be killed by the harvest machinery and incorporated into the baled hay. Cantharidin is a very stable compound and remains toxic even in the dead and dried blister beetles that may contaminate alfalfa hay. Since blister beetles often occur in large groups, or swarms, within a field, dead beetles can be concentrated in a small portion of the bales. Cantharidin causes irritation of the lining of the digestive and urinary system in horses. The number of beetles that result in illness is variable and depends on the sex and species of blister beetle and on the age, weight, bred and general health of the horse. The estimated number of ingested beetles that would be lethal to a horse ranges from 50-545. Identification. Blister beetles are elongated, soft-bodied beetles that vary in length from ½ to 1¼ inches. There are many species of blister beetles and their colors vary from black, brown or gray to striped or spotted forms with a combination of colors. Photos of many of the blister beetle species found in Texas are posted at http://texasento.net/TXMeloidae.html. Blister beetles have long antennae and legs. When viewed from above, blister beetles have a constriction between the back of the head and the thorax, creating a neck-like appearance.

Blister Beetles (Coleoptera: Meloidae) of Wisconsin
BLISTER BEETLES (COLEOPTERA: MELOIDAE) OF WISCONSIN: DISTRIBUTION AND ECOLOGY By Daniel A. Marschalek A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Entomology) at the UNIVERSITY OF WISCONSIN-MADISON 2013 Date of final oral examination: 12/7/12 The dissertation is approved by the following members of the Final Oral Committee: Daniel K. Young, Professor, Entomology Daniel L. Mahr, Professor Emeritus, Entomology Claudio Gratton, Associate Professor, Entomology Eileen M. Cullen, Associate Professor, Entomology Don M. Waller, Professor, Botany Mark E. Berres, Assistant Professor, Animal Sciences i BLISTER BEETLES (COLEOPTERA: MELOIDAE) OF WISCONSIN: DISTRIBUTION AND ECOLOGY Daniel A. Marschalek Under the supervision of Professor Daniel K. Young At the University of Wisconsin-Madison Meloids are commonly referred to as “blister beetles” due to the toxin (cantharidin) they possess which can cause blistering of human skin. Several meloid species have long histories of negatively impacting agriculture resulting from large foraging aggregations and negatively impacting livestock health. Even with these important and interesting aspects, little is known about these beetles in their natural habitats. There are recent faunistic surveys of selected insect taxa in Wisconsin but a formal investigation of Meloidae is lacking. The blister beetle fauna of several states has been published, but this survey represents the first in the Midwestern United States. This study provides a comprehensive list of all meloid species documented from Wisconsin, as well as taxonomic keys and summaries for each species (species pages) which includes taxonomy, description, and natural history. During this survey, 28 species in seven genera were documented in Wisconsin, with 10 species considered new state records.

Rice Extension Entomologist Iowa State University Potato Leafhoppers: Traditional Pests of Alfalfa The potato leafhopper, Empoasca fabae, is one of the most destructive pests of alfalfa. Adults and nymphs can reach population densities that decrease alfalfa yields by 50 percent or more, alter nutritional quality, delay harvest schedules, and decrease stand regrowth capabilities. Adult hoppers are small, 1/8-inch long, greenish yellow, wedge-shaped insects, which can fly or jump rapidly. The nymphs resemble adults in shape and color but lack wings. Damage to alfalfa occurs when leafhoppers inject their needle-like mouthparts into the plant and remove plant juices.

SCAN June 2021 Newsletter
June 2021 Hello SCAN members! The now-annual trek to the Francis Marion National Forest over Memorial Day weekend was another great success! Campers and day-trippers found plenty of places to explore across Berkeley and Charleston Counties. We concentrated our efforts on Washo Reserve on Saturday. The weather was nice and hot on Friday and Saturday, with sunny skies and highs in the 90ies. Rain moved in Saturday night and cooled everything down to the low 80ies for Sunday and Monday. Washo Reserve attendees included: Alison Smith Hal Giles Kim McManus Sharleen Johnson Cynthia Giles Jerry Bright Lee Morris Sharon Watson Dave Schuetrum Joe Long Marcus Sizemore Fred Martin Kathy Boyle Michael Crawford FMNF explorers also included: Eddie Hade Jeff Holmes Paul Kalbach Tess Moody Greg Ross Mandy Johnson Sharon Johnson Ty Hade Ian Deery Parker Gibbons Stephen Crotts Jackie Holmes Patrick Hade Stephen Prior Throughout the weekend, groups traveled the dirt roads of the Francis Marion National Forest, looking for snakes, toads, turtles, birds, and anything else that caught their fancy. Highlights included finding a beautiful Corn Snake, two Pygmy Rattlesnakes, a crayfish, and lots of Yellow-crowned Night Herons. The Blue Flag Irises were blooming. Thistle plants ranged from budding to fully blooming to almost done, depending on which road we explored. Prothonotary Warblers and Northern Parulas competed for our attention. The Chuck Will’s Widows held nightly singing contests to the amusement and frustration of the tent campers. L to R: Prothonotary Warbler, Pygmy Rattlesnake, Eastern Tiger Swallowtail L to R: exploring Hell Hole Road; Paul Kalbach, Lee Morris and Michael Crawford documenting a turtle; White-tailed Deer On Saturday, we explored Washo Preserve in the Santee Coastal Reserve mostly on foot, with a few folks taking advantage of the vehicle-accessible roads.

Toxins of Animals) [Biological-Origin Toxins]
4: Zootoxins (toxins of animals) [Biological-origin toxins] Distinction should be made between poisonous animals – those with toxins in their skin or other organs and which are toxic on ingestion – and venomous animals – those with specialised structures for production and delivery of toxins (venoms) to prey species or adversaries. Halstead (1988) published a monumental review of poisonous and venomous marine animals. A world list of snake venoms and other animal toxins including bee venoms, sawfly toxins, amphibian and fish toxins has been compiled by Theakston & Kamiguti (2002). Animals acquire toxins by one of three methods (Mebs 2001): • expression of genes coding for the toxin structures • metabolic synthesis (production of secondary metabolites) • uptake, storage and sequestration of toxins produced by other organisms (microbes, plants, or other animals) References: Halstead BW (1988) Poisonous and Venomous Marine Animals of the World. 2nd revised edition.

Epicauta Atomaria and Other Epicauta Species (Coleoptera: Meloidae)
Epicauta atomaria and other Epicauta species (Coleoptera: Meloidae) This short description has been prepared in the framework of the EPPO Study on Pest Risks Associated with the Import of Tomato Fruit. The whole study can be retrieved from the EPPO website. EPPO (2015) EPPO Technical Document No. 1068, EPPO Study on Pest Risks Associated with the Import of Tomato Fruit. EPPO Paris [link] Africa Asia Oceania North America South-Central America and Caribbean Epicauta atomaria and other Epicauta species (Coleoptera: Meloidae) Why Epicauta spp. was identified in the EPPO tomato study as USDA (2013a) reported interceptions of adults on tomato fruit (without indication of species). There are many species of Epicauta in the Americas, which generally seem to be polyphagous on hosts in several families. E. atomaria seemed to be the most important pest from the literature available, and was mentioned in recent publications. However, other species were also mentioned in the literature in association with tomato. This record focuses on E. atomaria, and few data on other species are given in a table. Note: Adams and Selander (1979) provided a comprehensive review of part of Epicauta (vittata group), including their biology, hosts and distribution. Due to the volume of this publication, it was possible to exploit it all in this screening, but it could be used if these pests are further studies. Where EPPO region: absent. South America: Brazil, Argentina (Diaz de Almeida et al., 2009; Hallan, 2010). Diaz de Almeida et al., 2009 also mention Colombia but in relation to a list of several pests (it is not certain that they all are in Colombia).
