Larva/Nymph 5th instar: 114mm 1st instar: small black caterpillars with black spines on black or yellow dorsal knobs 2nd instar: dark yellow to yellow with black spines on black or yellow dorsal knobs 3rd – 5th instar: Large, bright green with black spines on dorsal knobs. Knobs on the thorax can be orange to red, abdominal knobs can be yellow, side knobs are pale blue. Adult 110 – 150mm Large moth with reddish-brown wing color, crescent shaped white spot with red outline on each wing. Abdomens are red and white striped on the dorsal (back) side, and white with black lines on the ventral (front) side. Pupa (if applicable) 101 – 127mm Gray or brown cocoon suspended between Largest moth in North branches. America Type of feeder (Chewing, sucking, etc.): Larvae: chewing. Adults do not feed. Host plant/s: Larvae feed on various trees and shrubbery. The list includes, but is not limited to, species of maple, oak/beech, alder/birch, hibiscus, berry trees, elm, willow/cottonwood, roses and many others. Description of Damage (larvae and adults): Larvae consumption is greater than most larvae due to their size. Fortunately, they feed in small numbers, usually sparse from one another so significant damage is usually not observed. References: Cercopia Moth. (2010).

PORTABLE OUTDOOR CAGES for MATING FEMALE GIANT SILKWORM MOTHS (SATURNIIDAE)L
VOLUME 30, NUMBER 2 95 PORTABLE OUTDOOR CAGES FOR MATING FEMALE GIANT SILKWORM MOTHS (SATURNIIDAE)l THOMAS A. MILLER 2 AND WILLIAM J. COOPER ~ U. S. Army Medical Bioengineering Research and Development Laboratory, USAMBRDL BLDG 568, Fort Detrick, Maryland 21701 Like many lepidopterists who colonize and study the saturniids, we must find time apart from professional duties and other daily activities to pursue our interest in this family of moths. Therefore, our rearing methods must be both efficient and reliable if we are to accomplish any thing other than the mere maintenance of colonies. Although most of the saturniid species we have reared can be colonized for many genera tions without difficulty, we have at times had a particular problem obtain ing fertile eggs to perpetuate existing colonies or to begin new ones. This problem has been a function largely of limited available time to ensure the mating of females either by hand mating or by the use of indoor cages. For this reason we undertook an evaluation of methods for the routine, unattended mating of female saturniids indigenous to our area. We decided beforehand that the tying out of virgin females and the use of various-size stationary cages or traps (Collins & Weast, 1961; Quesada, 1967; Villiard, 1969) were not suitable to meet our requirements. Our approach, therefore, was to construct and test a series of portable out door cages that could be substituted locally for tying out or stationary cages and could also be easily transported for use in remote field areas. These cages were designed to minimize or prevent the escape of females placed therein while permitting pheromone-seeking males access for the purpose of copulation.

JOURNAL OF THE LEPIDOPTERISTS' SOCIETY Volume 39 1985 Number 2 Journal of the Lepidopterists' Society 39(2), 1985, 65-84 MAINTAINING SPECIES INTEGRITY BETWEEN SYMPATRIC POPULATIONS OF HYALOPHORA CECROPIA AND HYALOPHORA COLUMBIA (SATURNIIDAE) IN CENTRAL MICHIGAN JAMES P. TUTTLE 728 Coachman #4, Troy, Michigan 48083 ABSTRACT. The available literature suggests that Hyalophora cecropia and Hya lophora columbia have identical ethological requirements with respect to reproductive behavior and F j hybrids have often been produced in the laboratory. As a result, investi gators have long been puzzled by the rarity of natural hybrids since the two species occur sympatrically over much of the northern Great Lakes region. Field observations in Montcalm County, Michigan, identified a series of progressive barriers which operate to prevent hybridization. The prezygotic isolating mechanisms, seasonal isolation, daily allochronic flight behavior, and mechanical incompatibility re strict most of the interaction between the two species. However, when individuals oc casionally overcome those barriers and a successful hybrid mating occurs, several post zygotic isolating mechanisms are then tested. As a result of the overall effectiveness of these systems, the gene pool of each species is protected, thereby allowing the two species to co-exist. The large moths of the genus Hyalophora (Saturniidae) are repre sented by two species within the state of Michigan. The cecropia moth, Hyalophora cecropia (L.), is widely distributed, while Hyalophora co lumbia (S. I. Smith) is a much more localized species. When Moore (1955) published his checklist of the Michigan moths, he listed 18 county records for H. cecropia from such varied locales as Dickinson County in the western portion of the Upper Peninsula to metropolitan Wayne County in the southeastern portion of the Lower Peninsula.

Insect Immunity
INSECT IMMUNITY: INDUCIBLE ANTIBACTERIAL PROTEINS FROM HYALOPHORA CECROPIA Dan Hultmark University of Stockholm Dept. of Microbiology S-106 91 Stockholm Sweden INSECT IMMUNITY: INDUCIBLE ANTIBACTERIAL PROTEINS FROM HYALOPHORA CECROPIA Dan Hultmark Stockholm 1982 Doctoral Thesis for the Degree of Doctor of Philosophy at the University of Stockholm 1982 This thesis is based on five papers; references (1-5) in the reference list. ABSTRACT - A powerful bactericidal activity can be induced in the hemolymph of many insects as a response to an injection of bacteria. The nature of the effector molecules of this immune response was investigated, using pupae of the Cecropia moth, Hyalophora cecropia. Three major types of antibacterial proteins were found: the cecropins, the P5 proteins, and lysozyme. They appear in the hemolymph as a result of de novo synthesis. Six different cecropins were purified and characterized. The full amino acid sequences of the three major cecropins A, B and D were determined, as well as partial sequences of the three minor cecropins C, E and F. The cecropins are all very small (M = 4,000) and basic (pi > 9.5) proteins, and they show extensive homology in the if sequences. The three major cecropins are products of different genes. Their C-terminals are blocked by uncharged groups, which can be removed by mild acid hydrolysis. The minor cecropins are closely related to the major forms, and may be unblocked precursors or, in one case (cecropin F), a minor allelic form. The cecropins were shown to be lytic, and to be efficient against several Gram positive and Gram negative bacterial strains, but not against mammalian cells.

Chapter 2. the Effects of Compsilura Concinnata, an Introduced Generalist Tachinid, on Non-Target Species in North America: a Cautionary Tale
ASSESSING HOST RANGES OF PARASITOIDS AND PREDATORS _________________________________ CHAPTER 2. THE EFFECTS OF COMPSILURA CONCINNATA, AN INTRODUCED GENERALIST TACHINID, ON NON-TARGET SPECIES IN NORTH AMERICA: A CAUTIONARY TALE J. S. Elkinton and G. H. Boettner Deptartment of Plant, Soil and Insect Science: Division of Entomology, University of Massachusetts, Amherst, MA 01003 USA [email protected] INTRODUCTION Classical biological control has long been a principal weapon in the worldwide effort to com- bat the devastating effects of invasive species. Classical biological control involves locating natural enemies of invasive species in their native range and releasing them in the newly invaded habi- tat. The premise of classical biological control is that invasive species out-compete native spe- cies and become major pest problems in large part because they have become isolated from the suite of natural enemies that keep them in check in their native habitat. There have been many successes worldwide in the classical biological control of both invasive weeds and invasive arthropods. The advantages of classical biological control over any other approach are obvi- ous and well known: the control exerted is typically permanent; it requires little or no further intervention; it is thus highly cost effective compared to mechanical removal or use of chemical pesticides, which must typically be applied repeatedly and are often infeasible in forests or other natural habitats. Classical biological control of invasive weeds has had a long history of evaluating the host range of candidates for introduction. The obvious reason is that herbivorous natural enemies might become important pests of agricultural crops or other beneficial plants.

Gallice2 Introduction The cecropia moth, Hyalophora cecropia Linnaeus, is among the most spectacular of the North American Lepidoptera. It is a member of the Saturniidae, a family of moths prized by collectors and nature lovers alike for their large size and extremely showy appearance. Adults are occasionally seen attracted to lights during spring and early summer, a common habit of many moths. It is unclear exactly why these insects visit lights, although a number of theories exist. One such theory posits that artificial lights interfere with the moths’ internal Figure 1.
