INSECT ANATOMY UP CLOSE Order #481..........$42.50
Revised 1999

Fascinating close-up photography explores the external anatomy of insects,
illustrating both typical and modified structures. Come face to face with a yellowjacket,
examine the scales on a butterfly's wing, find out how flies are able to walk on the
ceiling, see how bees carry pollen, study the various types of mouth parts, and much
more--makes the study of insect anatomy a stimulating experience. 2O slides and
detailed guide.

CONTENT SAMPLE: 21995 Insects display a tremendous amount of variation among
their ranks but all have the same basic design. This dragonfly (order Odonata) will serve as our
model insect. Insects have three basic body regions: the head, the thorax and the abdomen.
The exoskeleton of each of these regions is composed of several plate-like structures called
sclerites. With the exception of those comprising the head capsule, the sclerites are joined
together by a membranous tissue which enables them to flex in relation to one another.

The head capsule is composed of a number of sclerites which are fused together and
thus are not always distinct. The head is the center of feeding and vision. On the head we find
two eyes, two antennae and the mouth parts. Internally, there is a brain and a throat that leads
into the digestive tract.

The thorax is the region between the head and the abdomen and is the center of
locomotion. Here we find three pairs of legs and, typically, two pairs of wings. The thorax has
three basic segments, each of which is made up of two or more sclerites. The first segment,
the prothorax, lies directly behind the head and bears one pair of legs. The middle and last
segments, the mesothorax and metathorax respectively, each bear one pair of legs and one
pair of wings (if present).

The abdomen lies directly behind the thorax and is usually the largest body region.
The abdomen of insects may be globular or long and slender, or any of numerous variations in
between. Typically, there are 10 or 11 segments in this region, although some insects have
fewer. In most insects, the abdomen is the least interesting region externally. Internally,
however, the abdomen plays a major role in the functions of respiration, circulation, digestion
and reproduction.

INTRODUCTION TO THE INSECTS Slides order #SS-0705S........$44.95

A visual study through skilled artwork of a large and varied group of organisms
that have a critical impact on the environment and on man. Coverage includes external
and internal anatomy, development, life cycles, adaptive modifications and social
insects. 23 slides and detailed guide. (Filmstrip order SS-0705F........$15.00.)

CONTENT SAMPLE: 11. Insects are sensitive to light, sound and chemical stimuli and
often temperature, humidity and gravity as well. In a sense, insects are shut off from the world by
their hard outer skeleton, yet they have evolved a magnificent array of sensory mechanisms other
than eyes, nose, mouth and skin.

Scattered over the mouth parts, legs and body and especially the wings and antennae
are hairs or spines protruding through (often a part of) the cuticle. These are primarily organs of
touch. Each hair is supplied with a nerve which conducts the impulse of bending to the proper
ganglion. Ground vibrations and air currents are detected by these special hairs. That's why
it is difficult to swat a fly with a rolled-up newspaper. These tiny sense hairs respond to the
approaching weapon by bending to the displaced air mass.

Taste and smell are chemical senses and insects have numerous receptors for each.
Taste is generally confined to the mouth parts although flies, for example, taste some food by
walking on it. The taste hairs of the mouth have three receptor cells at the base--one for touch,
one to detect sugars and a third for unappetizing chemicals. Some hairs fire quickly while others
are slow to respond. This method always leaves some hairs ready to work so that taste isn't
overwhelmed and inactivated for a time. Smell is highly refined in the insects. Generation after
generation, insects return to the same flowers or trees their ancestors fed upon, attracted by the
peculiar chemical or mixture of chemicals manufactured by the plant.

DISSECTION GUIDE FOR THE GRASSHOPPER Slides order #SS-0595S.......$24.95

Avoid smelly and controversial classroom dissections and the needless
depletion of wild populations yet still teach biology fundamentals. 1O frames. (Filmstrip
order SS-0595F.....$15.00.)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

DISSECTION GUIDE AND SURVEY OF ARTHROPODS Slides order #SS-0050S.....$49.95

A guide and survey of common arthropod species including a brief overview of
the grasshopper and crayfish. Reference is also made to trilobites, horseshoe crabs,
fairy and brine shrimp, daphnia, ostracods, copepods, barnacles, isopods, crabs,
dragonflies, butterflies, termites, flies, and centipedes. 3O frames and guide. (Filmstrip
order SS-0050F...$15.00.)

CONTENT SAMPLE: 6. The arthropod digestive tract is a long tube that is generally
divided into a foregut, midgut and hindgut--each of which is specialized, depending on the diet and
method of feeding. The midgut is often associated with digestive glands or outpocketings (caeca)
which increase the surface area for enzyme secretion and nutrient absorption.

Lab Pack of 5 Order #CDR-1321-5....$149.95

40-minute multimedia Presentation -:- Easy going narration with hundreds of interactive links
Very extensive supplemental information (over 15,000 words!)

100 interactive Questions with Explanations, and automatic Quizzes
Customized electronic Glossary -:- Additional Free Dictionary and Encyclopedia

The significance of the class Insecta, the largest and most familiar class of arthropods. The 34
orders of insects contain over a million species which inhabit almost every nook and cranny on
earth. Three out of four species of animals belong to the phylum Arthropoda, yet only insects, of
all the Arthropoda, have attained the ability to fly. This colorful and unique program il-lustrates the
great range and variety of insect adaptations, elaborately details their development and anatomy,
and portrays their great diversity. Photographic coverage of live insects is very comprehensive and
wide-ranging. Scientific names are provided. Some of the impact insects have on humans, and
even some folklore, is also presented.

An easy going, highly informative interactive narrative linked to a very extensive supplemental text
provides easily accessible, near encyclopedic information about every animal—right at the user’s
fingertips! Additional interactive features access over 100 questions with explanations, automatic
quizzes and a customized glossary.

Among the many insects and insect stages covered in this program are beetles, silverfish,
springtails, caddisflies, dragonflies, mayflies, grasshoppers, cockroaches, mantis, walking stick,
termites, lice, true bugs, cicadas, aphids, ladybird, dobsonfly, long-horned pine sawyer beetle,
dung beetle, moths, butterflies, mosquitoes, maggots, horsefly eye, fleas, bees, egg, larva, pupa,
cacoon and caterpiller. Differences in development and types of metamorphosis provide the basis
for insect classification into subclasses. These variations are presented here as well. In addition,
the physical and functional differences that occur in social insects like termites, ants and bees
resulting in castes, are also detailed.

Included free on this disk, greatly enhancing its value as a reference tool, are Webster’s New
World Dictionary (Third College Edition) featuring more than 150,000 entries and the American
Concise Encyclopedia with more than 15,000 entries and original source documents.
