THE COVER PICTURE is a photograph, taken by the author, of a rhinocerus beetle of the genus Dynastes, from Costa Rica. The specimen is in the insect collection of the Department of Eutomology of Kansas State University, Manhattan. The picture is about twice the actual size of the insect. Rhinocerus beetles of other genera are found in the southern states. The family Scarabeidae, to which these belong, also includes the common Kansas June bettles or May beetles, often incorrectly called June "bugs."

"Where the bee sucks, there suck I, In a cowslip's bell I lie." Bees were known long before Shakespeare, as were other insects. Bees are and were important for their honey and wax. Bees are only one kind of the multitude of insects we know today. Many of the well-known insects are known for the damage done to farm crops, garden crops, and household goods. Yet not all of these other insects are harmful; many help man in his activities.
What is an insect? How are they classified? Where are they found? What do they eat? How would you collect them? What are some of the common representatives? In the following paragraphs and in the tabular summary on page 10 to 15, these and other questions will be answered.
WHAT IS AN INSECT?
"Bugs" is the common term often used to describe any insect. It is incorrect in general usage because a bug represents one particular group of insects, the "true bugs" of the Order Hemiptera. The box-elder bug (page 12) belongs to this order. Insects are small invertebrate animals that are relatives of the Kansas crayfish and also of the ocean crabs and lobsters. The insect body, which is covered by a hard outer layer, has three sections or regions: head, thorax, and abdomen. A pair of bulging compound eyes are located on the front or upper side of the head. Simple eyes, ocelli, are sometimes present. If wings are present, they are attached to the middle or thoracic region, where the legs are also attached.
The "jaws" or mouthparts, of an insect are in two pairs. Grasshopper jaws are modified for biting and chewing. Butterflies, on the other had, have a long tube or proboscis, formed from these jaws to suck the nectar from flowers. The antennae are located on the head, either above or between the compound eyes. The antennae are of varying lengths in different species of insects. Some antennae resemble feathers, some movable pieces of string and others so short that they are almost invisible. Most insect antennae are used to touch and feel, much as we use our fingers.
Three pairs of walking legs are attached to the thorax or middle body region. The hind pair may be used to jump. The wings are also attached here and may be in one or two pairs.
Reproductive organs of most insects are found within the abdomen and at the end of the abdomen. The males may have organs for clasping the female during fertilization, and the female an ovipositor through which she lays eggs.
Other animals closely related to insects are spiders, centipedes, and millipedes. These differ from insects in body form, number of legs per body segment, mode of reproduction and number of antennae.
Insects have antennae, three pair of walking legs, tracheal tubes instead of lungs for breathing, and three body divisions. Spiders lack antennae, possess four pair of walking legs, "lungs" for breathing, and two body regions.
Centipedes and insects are related, but separated by a number of body divisions and the number of legs and position of the leg attachment. Three body regions with the three pairs of legs attached to the middle one characterize insects, while the centipedes have many segments not defined into distinct portions and with one pair of legs per each segment.
Millipedes have many segments with two pairs of walking legs on each and no antennae, while insects have three body regions and antennae.
HOW ARE INSECTS CLASSIFIED?
The classification system of insects follows the typical zoological grouping into various categories. For example, the honey bee has this scientific classification:
The large number of insect species causes great difficulty in the use of specific categorical names except by expert entomologists. Even experts often use common names for insects.
The Class Insecta is typically characterized by the following:
- three body regions,
- three pairs of walking legs
- wings in the adult stage of the life cycle,
- some form of metamorphosis in the development of the individual. There are some exceptions to all except the first of these.
Subdivision of the Class Insecta into orders is based on characteristics such as: 1. types of metamorphosis, 2. number and type of wings, 3. type of "jaws" or mouthparts, 4. structure of the external portions of the reproductive system. Further separation into families, genera, and species is on the basis of more detailed features, such as: 1. type of pupal case, as in caddisflies, 2. shape of antennae, as in beetles, 3. chrysalis or cocoon in the pupal stage, as in moths and butterflies.
HOW MANY KINDS ARE THERE?
Insects comprise by far the largest class of animals in the world. More than 600,000 species have been described, and possibly as many as a million more species remain to be identified. Most estimates agree that between three-fifths and seven-eights of all the animals in the world are insects. The class Insecta has been divided into about 25 orders; more or fewer, depending on the classification system used. The beetles, one of 25 orders, may include as many as 250,000 species in the world, and are represented by 15,000 to 18,000 species in Kansas. There are more species of beetles than there are of all other species of animals, excluding the insects.
WHERE ARE INSECTS FOUND?
Insects of some kind are found everywhere on the earth with the exception of the cold polar ice caps and the open ocean. Butterflies have been found within the Arctic Circle, and a few primitive insects are known in Antarctica. Large numbers of insects are found in the tropics. Kansas insects are of course characteristic of those of the temperate regions.
Many adult insects, especially beetles, the larval stages of many species, and some pupae are found in the soil. Many beetles, dragon flies, mosquitoes, midges, and caddisflies are found in or near water. Many grasshoppers, katydids, true bugs, beetles, flies, and ants are found on plants, telephone and highline poles, and houses. Other insects are found burrowing into fruit, in plant stems, in garbage dumps, and in the wood of your houses. The clothes in your closet and the papers in your garage are other places where insects may be found.
One of the best places to collect insects is in the flowers of your garden or yard. Flowers attract moths, butterflies, bees, ants, wasps, flies, and even beetles and true bugs. Many different kinds and sizes of insects may be found with a little effort.
Shores of ponds and streams are good places to find dragonflies, damselflies, whirlygig beetles, water striders, toad bugs, scavengers, and water boatmen. Other insects, such as butterflies and moths, may be found here also.
Many beetles and true bugs may be found on the ground; under leaves, boards, and stones, or in rotten logs or dung. Many beetles are associated with decaying flesh, along with fly larvae.
Parts of plants, other than flowers, have many insects associated with them. Many insects may be found resting, laying eggs, or using the plants for shelter.
The most productive place to collect numbers of insects is around a light in the summer. Many flying, crawling, or hopping insects collect around a light and are easily picked up. As many as fifty species of insects may be collected in a single evening.
HOW DO INSECTS REPRODUCE?
Insect reproduction is similar to that of other animals. The sexes of most species are separate, male and female. Eggs produced by the female usually develop after fertilization, but rarely by parthenogenesis (development of eggs without fertilization). The eggs are either laid by the female with hatching occurring later, or the female retains the eggs within the body until they hatch and Jiving young are produced.
The development of the young after hatching follows one of four courses:
- the young resemble the adult except in size, that is, no metamorphosis occurs;
- the young resemble the adults, but wings appear only after a period of development (gradual metamorphosis);
- the egg hatches into a larval nymph or naiad that is markedly different from . the adult (incomplete metamorphosis);
- the larva which changes to the pupa develops into the adult after a period of resting (complete metamorphosis).
Refer to the accompanying drawings for a summary of these types.
WHAT DO INSECTS EAT?
Insects enjoy a variety of food, just as you do. They feed on leaves and stems of plants, juice from the stem, or nectar from the flowers of living plants. Many beetles eat rotten wood, primitive plants found in rotten wood, dung, roots of other plants, and also foliage. Some insects, especially wasps, are parasitic upon other insects. Mosquitoes and some flies are known to suck blood from animals, including man. For each living or dead plant or animal, there is an insect waiting to eat it.
HOW DO YOU COLLECT INSECTS?
There are many ways to collect insects. You may pick them up by hand, catch them with an insect net, or in a variety of traps.
The simple cloth insect net may be used to catch most flying insects. Nearly everyone has seen some happy "bug hunter" chasing a butterfly or dragonfly. Traps of various sorts are simple to construct and effective to use.
The simplest trap to construct is a sheet of white material draped from a tree with a light bulb behind it. Hanging a bulb over a pail of water will collect many insects. A piece of paper attached to a wall, with the outer end bent into a V will funnel insects into a collecting jar. A mixture of molasses and sugar or syrup and sugar will attract moths if placed on trees on a summer evening.
A pamphlet entitled How to Make an Insect Collection may be obtained from Ward's Natural Science Establishment, Inc., Rochester, New York. The Field Book of Nature Activities by William Hillcourt, has an extensive section on insect collections. Both of these references give many ways to construct traps.
WHAT GOOD OR HARM ARE THEY?
Not all insects are harmful. On the contrary, only about one per cent of the known species are harmful. In Kansas, the harmful insects for which control measures are used number only 100 species.
The other 99 per cent may be classified as beneficial. The beneficial insects are helpful in a number of ways; they may feed upon, parasitize, or otherwise destroy the harmful ones; they may furnish us with food; or they may furnish us a service that is far more important: pollination.
Pollination of farm, garden, and fruit crops is carried on to a large extent by insects. Bees, flies, and a few other insects carry pollen from one flower to the next in their search of nectar. Without the bees, alfalfa, many garden flowers, and other wildflowers are not pollinated. Fruit trees are pollinated by many kinds of insects.
THINGS TO DO
- Collect the insects from the home garden.
- Collect the insects from a field or woods.
- Compare the insects from the garden and woods.
- Construct an insect observation cage.
- Start and maintain an ant colony.
- Collect the butterflies from your school yard.
- Find a butterfly pupal case and follow its development.
- Imbed the insects from your area in plastic.
- Visit the insect collection at a college or university.
- Make an insect net. The one shown is made of a wire coat hanger, a piece of cheesecloth or other open-weave cloth, and a broomstick handle.
- Make an insect cage. The following instructions are quoted from the December, 1958 issue of The Kansas School Naturalist:
- two round cake pans or pie tins
- screen wire or staples
- plaster of Paris
- small branch
Make a cylinder of the screen, of the right size to fit into the pan or tin to be used. Overlap the edges of the screen and fasten with wire or staples.
Make a mixture of water and plaster of Paris and pour into one pan or tin. At the point of solidification, press the screen cylinder into the plaster of Paris; also insert the branch into the plaster of Paris, in the position it is to occupy after the plaster hardens.
Use the other pan or tin to put on top of the cylinder, to serve as a lid. Modifications of this type of container can be made by using different shapes and sizes of pans. Small containers which children can take with them on field trips can be made from pint ice cream cartons, or similar containers:
