Butterflies and Moths up Close! Butterflies and Moths Up Close! Butterflies and moths comprise a group of insects named Lepidoptera. Lepido- means scaly and -ptera wing, so they are literally named the scaly winged insects. If you were to draw a family tree of every scaly winged insect in the world one branch on the tree would include all of the butterflies, with everything else being a moth. monarch butterfly (Danaus plexippus) luna moth (Actias luna) Here we have two specimens, a monarch butterfly on the left and a luna moth on the right. We’re going to take a closer look at their wings, heads, and antennae to explore their similarities and differences, but first let’s observe each as a whole. What do you notice about them?

The head is where you can find an insect's eyes, antennae, and mouth. We will take a closer look at the antennae, for now focus on the eyes and the mouth. Both of these specimens have two large compound eyes, and most butterflies and moths have long straw-like mouthparts called a proboscis. The monarch butterfly has its proboscis curled up and tucked away. Can you find any mouth parts on the moth? If you can’t, do not fret because it doesn’t have one! While most moths do have a proboscis, those of the royal silk moth family do not. They have to do all of their eating as a caterpillar because after that, they’re done eating for the rest of their lives. What do you think a butterfly eats? Remember butterflies drink through a straw-like mouth part, called a proboscis. Think of three sweet things that a butterfly might drink with their proboscis and write them below.

They come in all shapes and sizes depending on the kind of insect. Antennae are the best way to tell butterflies and moths apart. Almost all butterflies have what are called clubbed antennae. You can see the monarch butterfly antenna on the left is long and thin until it thickens into a club shape towards the end. Moths, on the other hand, have many different kinds of antennae. They can be thick, thin, or even feathery like the luna moth pictured on the right, but they are never clubbed. Now that we’ve explored what antennae look like, are you wondering what they do? They are sensory organs that help insects observe their surroundings. Insects can use their antennae to smell, taste, touch, and sense vibrations. Butterflies are also able to taste using their feet! How does this compare to how you sense the world around them? Compare yourself to the butterfly below! Fill in the chart to compare the human and butterflies body parts associated with each sense.

  • Moth Fun Facts
    MOTH FUN FACTS NC has 174 species of butterflies, and 2,000-2,500 moths! That’s 11 to 14 times as many moth spe- cies as there are butterflies. There is moth caterpillar that is carnivorous, the Ashen Pinion, Lithophane antennata which is a well-known predator of winter moths. Some tiger moths in the family Arctiidae are known to "jam" bat echolocation by producing sounds. The North Carolina Heritage Program lists 99 state concern moths mostly from the mountains, sandhills and coast. Many females of the Tussock family of moths don't have wings. The Hawk moth (Sphinx) is the worlds fastest flying insect attaining speed of over 50 kph Moth antennae are either feather like or a hair like filament. The Cecropia moth is North America's largest insect with a six inch wingspan. Moths have hairy bodies to help retain internal body temperature necessary for flight. Quite a few moths fly during the day, such as the Hummingbird Clearwing, Virginia Ctenucha and the Spear-Marked Black. In colder climates some moths can have a two year life cycle. Some moth caterpillars, such as the "Io" are covered with stinging hairs. Moths make up 80 percent of the order lepidoptera. A small group of moths are called "Bird Dropping" moths because -you guessed it- that's what they resemble when they are at rest. Moths navigate by two methods. They use the moon and stars when available and geomagnetic clues when light sources are obscured. Cloth Moths eat such things as wool, fur and other animal products.

  • Impacts of Native and Non-Native Plants on Urban Insect Communities: Are Native Plants Better Than Non-Natives?
    Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives? by Carl Scott Clem A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Key Words: native plants, non-native plants, caterpillars, natural enemies, associational interactions, congeneric plants Copyright 2015 by Carl Scott Clem Approved by David Held, Chair, Associate Professor: Department of Entomology and Plant Pathology Charles Ray, Research Fellow: Department of Entomology and Plant Pathology Debbie Folkerts, Assistant Professor: Department of Biological Sciences Robert Boyd, Professor: Department of Biological Sciences Abstract With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled with replacement of native plants by alien ornamental plants such as crepe myrtle, Bradford pear, and Japanese maple. Two projects were conducted for this thesis. The purpose of the first project (Chapter 2) was to conduct an analysis of existing larval Lepidoptera and Symphyta hostplant records in the southeastern United States, comparing their species richness on common native and alien woody plants. We found that, in most cases, native plants support more species of eruciform larvae compared to aliens. Alien congener plant species (those in the same genus as native species) supported more species of larvae than alien, non-congeners. Most of the larvae that feed on alien plants are generalist species. However, most of the specialist species feeding on alien plants use congeners of native plants, providing evidence of a spillover, or false spillover, effect.

    INTERNATIONAL ASSOCI ATION OF BUTTERFLY EXHIBITORS AND SUPPL IERS Volume 16 Number 3 MAI– JUNE 2017 Visit us on the web at www.iabes.org Special edition: moths Interview with Bart Coppens, guest speaker at ICBES 2017 Who are you? I’m Bart Coppens (24) from the Netherlands – a fervent breeder of moths and aspiring entomologist. In my home I breed over 50 species of moths (mainly Saturniidae) on yearly basis. My goal is to expand what started out as a hobby into something more scientific. It turns out the life cycle and biology of many Saturni- idae is poorly known or even unrecorded. By importing eggs and cocoons of rare and obscure species and breeding them in cap- tivity I am able to record undescribed larvae, host plants and the life history of several moth species – information that I publish on a scientific level. My ambition is also to gradually get into more difficult subjects such as the taxonomy, morphology and evolution and perhaps even the organic chemistry (in terms of defensive chemicals) of Saturniidae – but for now these subjects are still beyond my le- Bart with Graellsia isabella vel of comprehension, as relatively young person that has not yet completed a formal education. I’d also like to say I have a general passion for all kinds of Lepidoptera, from butterflies to the tiniest species of moths, I truly like all of them. The reason I mention Saturniidae so much is because I have invested most of my time and expertise into this particular family of Lepidoptera, simply because this order of insects is too big to study on a general scale, so I decided to specialise myself a little in the kinds of moths I find the most impressi- ve and fascinating myself – and was already the most familiar with due to my breeding hobby.

  • Like a Moth to a Flower
    Like a Moth to a Flower Moths After dark, moths, as well as bats, take over the pollinating night shift. Nocturnal bloomers, with pale or white flowers heavy with fragrance and copious nectar, attract these pollinators. Some moths are also active by day. Moths and Butterflies Butterflies, possibly the best loved of all insects, are appreciated as benign creatures that add color, beauty, and grace to our gardens. Moths, on the other hand, aren’t nearly as appreciated for their pollinating contributions. Butterflies and moths belong to the same insect order, Lepidoptera. Can you tell the difference between a moth and a butterfly? In general, butterflies are brightly colored, and fly by day, and moths are more likely to be grey or brown, and fly at night. But there are numerous exceptions: such as bee-mimicking hawkmoths, colorful luna moths, and colorful, day-flying scape moths. At rest, butterflies tend to hold their wings either partially open or closed vertically over their bodies (like the sails of tiny sail boats). Most moths, however, hold their wings flat. Moths tend to be fatter and hairier than butterflies. And moths’ antennae are often broad, complex and feathery, while butterflies generally have simple antennae with clubbed tips. Metamorphosis Like a butterfly, a moth begins life as an egg laid on or near its host plant. The egg hatches into a tiny caterpillar, eating and growing until it transforms into a chrysalis. They go through complete metamorphosis into sexually active, winged adults. Some moths spin a cocoon from their silk glands, creating an additional layer of protection.
