Butterflies have visual pigments that let Flying Colours them detect ultraviolet wavelengths. Some males have ultraviolet markings on their wings that they use to attract females. There are no colours in the dark! Butterflies’ splendid hues show up Subtle ultraviolet markings when light hits the thousands of tiny scales that make up the distinctive markings on their wings.

2021 US Dollars Butterfly Pupae to the Butterfly Keeper January 2021 2021 Butterfly Pupae Supplies
2021 US Dollars Butterfly Pupae To the Butterfly Keeper January 2021 2021 Butterfly Pupae Supplies Happy New Year, thank you for downloading our 2021 US$ pupae price list and forms. Last year was a challenge for everyone and the damage caused by the pandemic to the Butterfly trade was considerable. Many facilities were forced to close their doors to the public and therefore received no income. We ourselves had to shut for seven months out of twelve and as I write in January there is no sign of us being allowed to open in the next two months at least. This hardship has been multiplied in the situation of our suppliers as they have no government support. IABES did manage to get some financial support to them during the first extensive lockdown but spread over many breeders it could not replace the income they get from their pupae. Along with problems here and at source the airline industry is really struggling and getting what pupae we can use, onto a suitable flight has caused us many a sleepless night telephoning Asia at one extreme and South America at the other. However, we trust that we will come out of this global problem and be able revert to normal sometime during the spring. We still guarantee that all our pupae conform to all international standards and comply with all current legislation. We have a system in place that gets pupae to US houses in an efficient manner. We have had a very small price increase this year mainly because of increased airfreight costs.

MADAGASCAR: the Wonders of the “8Th Continent” a Tropical Birding Custom Trip
MADAGASCAR: The Wonders of the “8th Continent” A Tropical Birding Custom Trip October 20—November 6, 2016 Guide: Ken Behrens All photos taken during this trip by Ken Behrens Annotated bird list by Jerry Connolly TOUR SUMMARY Madagascar has long been a core destination for Tropical Birding, and with the opening of a satellite office in the country several years ago, we further solidified our expertise in the “Eighth Continent.” This custom trip followed an itinerary similar to that of our main set-departure tour. Although this trip had a definite bird bias, it was really a general natural history tour. We took our time in observing and photographing whatever we could find, from lemurs to chameleons to bizarre invertebrates. Madagascar is rich in wonderful birds, and we enjoyed these to the fullest. But its mammals, reptiles, amphibians, and insects are just as wondrous and accessible, and a trip that ignored them would be sorely missing out. We also took time to enjoy the cultural riches of Madagascar, the small villages full of smiling children, the zebu carts which seem straight out of the Middle Ages, and the ingeniously engineered rice paddies. If you want to come to Madagascar and see it all… come with Tropical Birding! Madagascar is well known to pose some logistical challenges, especially in the form of the national airline Air Madagascar, but we enjoyed perfectly smooth sailing on this tour. We stayed in the most comfortable hotels available at each stop on the itinerary, including some that have just recently opened, and savored some remarkably good food, which many people rank as the best Madagascar Custom Tour October 20-November 6, 2016 they have ever had on any birding tour.

New Method of Reducing Aero Acoustical Noise for a Quiet Propeller
Journal of Engineering Mechanics and Machinery (2019) Vol. 4: 1-28 DOI: 10.23977/jemm.2019.41001 Clausius Scientific Press, Canada ISSN 2371-9133 ‘Butterfly acoustical skin’ – new method of reducing aero acoustical noise for a quiet propeller Igor S. Kovalev Science and Technology Laboratory, Kinneret College, Emek Hayarden, 15132, Israel Correspondence: [email protected] Keywords: ‘butterfly acoustical skin’, moth, noise reduction, porous scales, propeller. Abstract: An experimental investigation was conducted on the effect ‘butterfly acoustical skin’ (metallic version of the lepidopterans scale coverage) on the acoustic performances of two - bladed propeller (diameter of 1200 mm, airfoil sections of NACA 2415, rotating speed of 1780 rpm, Re ≈ 2 × 105) in a low – speed straight through a wind tunnel. Attention was initially directed to this problem by observation of the porous scales and porous scale coverage of lepidopterans as well as other studies indicating the noise suppression of flying lepidopterans by wing appendages. The property of the moth coverage allows these insects to overcome bat attacks at night. These appendages are very small (size: 30 – 200 µm) and have a various porous structures. I discuss both many different micro – and nanostructures of the porous scales, and many differences in details among various structures of the porous scale coverage of lepidonterans. I consider here only porous scales of butterflies Papilio nireus, Nieris rapae, Deelias nigrina, male Callophrys rubi, male Polyommatus daphnis, butterfly Papilio palinurus as well as porous scale coverage of cabbage moth, moth of Saturniidae family and moth of Noctuoidea family. The evolutionary history of lepidopterans and the properties of lepidopterans scale coverage are briefly discussed as well as different methods of reducing aero acoustic noise of aircrafts.

Chapter 1 Introduction and Literature Review
Chapter 1 Introduction and literature review Nature has always been an invaluable source of inspiration for technological progress. Great scientific revolutions were started by the work of men such as Leonardo da Vinci and Galileo Galilei, who were able to learn from nature and apply their knowledge most effectively. The process of transferring the ingenious solutions evolved by some species into engineered devices is now an established and autonomous discipline known as biomimetics. Due to advances in the fabrication technologies of nanometer-scale optical devices, biomimetics has expanded into the field of non-classical optics. This gives an opportunity for engineers and zoologists to learn from nature in a mu- tually beneficial partnership. Engineers can draw inspiration from the ways in which Nature produces fascinating optical effects and zoologists can apply the quantitative theoretical methods developed in optical engineering to understand the phenomenology of their specimens. The development of expertise brought about by this interaction has already resulted in commercially available products. The surface of some optical discs for data storage and certain surface-relief vol- ume phase holograms share the designs and functionality of the microstructures found in the eye of moths and on the wings of butterflies. 1 Visual appearance is one of the areas in which nature has evolved smart optical solutions. Through interference of light reflected or diffracted by minute features, many organisms are able to generate structural colour. Different optical effects are generated by arrangements of biomaterial on the surface of various organisms. Amongst the many examples of structural colour found in nature, the beauty of the intense chromatic display of butterflies has strongly captured the interest of researchers.

Madagascar 2017
Field Guides Tour Report Madagascar 2017 Nov 6, 2017 to Nov 27, 2017 Phil Gregory & Doug Gochfeld For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. We started the tour in the virtually pristine rainforests of Ranomafana, which the group (along with Gerard at right and Baku at far left) is enjoying here just prior to our dusk search for mouse lemurs. Photo by guide Doug Gochfeld. This year’s Field Guides Madagascar tour was full of great features, including over twenty species of Lemur, more than one hundred species of endemic birds, and a litany of fascinating natural wonders and cultural insights. Indeed, there were so many highlights that there wasn’t widespread agreement about just what the favorite bird or mammal or experience of the trip was. We fared very well with the weather; we had some cool and cloudy conditions to relieve us from the unforgiving tropical sun in a couple of locations, and the periods of rain mostly kept away from our birding excursions. Other than the plague scare that wasn’t so scary after all, the bees of Andasibe, and a very minor Mad Air schedule change, the tour went off without so much as a hitch! This year, we started out by heading to Ranomafana National Park, one of the real jewels among Madagascar’s protected areas. Having this as our first stop means two days of mostly driving to start the tour, but to everyone’s credit, it was handled gracefully and without complaint. We managed to fit in a couple of very productive birding stops on the way south: on day one at a nice flooded rice paddy area, where we scored our only Madagascar Snipes of the tour along with a swirling mass of Plain (Brown-throated) Martins, and then on day two at the Reserve Villageoise D’Ankazomivady, where the highlight among introductions to several Madagascar endemic species was a scarce Baillon’s Crake! We spent an afternoon and then two full days exploring the rainforests around Ranomafana, including the “Circuit 2” trail on the way to Vohiparara.

Tympanal Ears in Nymphalidae Butterflies: Morphological Diversity and Tests on the Function of Hearing
Tympanal Ears in Nymphalidae Butterflies: Morphological Diversity and Tests on the Function of Hearing by Laura E. Hall A thesis submitted to the Faculty of Graduate Studies and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Master of Science in Biology Carleton University Ottawa, Ontario, Canada © 2014 Laura E. Hall i Abstract Several Nymphalidae butterflies possess a sensory structure called the Vogel’s organ (VO) that is proposed to function in hearing. However, little is known about the VO’s structure, taxonomic distribution or function. My first research objective was to examine VO morphology and its accessory structures across taxa. Criteria were established to categorize development levels of butterfly VOs and tholi. I observed that enlarged forewing veins are associated with the VOs of several species within two subfamilies of Nymphalidae. Further, I discovered a putative light/temperature-sensitive organ associated with the VOs of several Biblidinae species. The second objective was to test the hypothesis that insect ears function to detect bird flight sounds for predator avoidance. Neurophysiological recordings collected from moth ears show a clear response to flight sounds and chirps from a live bird in the laboratory. Finally, a portable electrophysiology rig was developed to further test this hypothesis in future field studies. ii Acknowledgements First and foremost I would like to thank David Hall who spent endless hours listening to my musings and ramblings regarding butterfly ears, sharing in the joy of my discoveries, and comforting me in times of frustration. Without him, this thesis would not have been possible. I thank Dr.
