DRAGONFLIES & LACEWINGS Order #465..........$42.50

Examines the behavior and importance of the Odonata and Neuroptera. Pictured
are dragonfly nymph and emergence; clubtail, skimmer, biddy and darner dragonflies;
damselfly nymph; narrow-winged, broad-winged and spread-winged damselflies;
damselflies mating; green lacewing (adult, eggs and larva); brown lacewing; fishfly (adult,
larva and pupa); snakefly; doodlebug and antlion. 20 slides and guide.

CONTENT SAMPLE: 21613 Damselfly nymphs share many of the same aquatic and
predatory habits of their larger cousins, the dragonfly nymphs. Both possess the highly modified
retractable labium used to seize prey. However, damselfly nymphs are more slender and have
three conspicuous leaf-like structures at the tip of the abdomen. These are gills and serve to
remove oxygen from the water for respiration. These gills are also used like paddles for
swimming, in the same manner as a fish uses its tail (caudal) fin. Dragonfly nymphs also
possess gills, but they are smaller and located internally.

REVIEWS: “The slides are accompanied by a well written text....The program will be
of interest to naturalists and educators...” Previews.

BRISTLETAILS, TERMITES, CADDISFLIES & OTHERS Order #466........$42.50

The smaller insects: silverfish, jumping bristletail, springtail, stonefly, earwig,
webspinner, sucking louse, chewing louse, booklouse, thrips, scorpionfly, caddisfly,
case-making and net-spinning caddisfly larvae, flea, subterranean termites, plus the
caste system of a colony of dampwood termites. 20 slides and guide.

CONTENT SAMPLE: 21534 Perhaps the most specialized caste of termites are the
soldiers, easily recognized by their large, rectangular heads adorned with a pair of powerful
mandibles. In some species, the soldiers' mandibles are so large that they cannot feed them-
selves and must be fed by the workers.

Note the small, white, bean-shaped objects surrounding this damp wood soldier. These
are the pupae of carpenter ants (family Formicidae: genus Camponotus). Both carpenter ants
and termites often live peaceably in the same tree in fact, some carpenter ants nest in the
abandoned galleries of termites. This particular soldier termite has apparently stumbled onto the
discarded brood chamber of a carpenter ant nest. Had this been an active brood chamber, it is
likely that the ants would have dispatched the termite, for carpenter ants are very protective of
their young.

INTRODUCTION TO BEETLES Order #467........$42.50

Introduces the order Coleoptera and details the habits and importance of many
beetle species. Includes tiger beetle, ground beetle, predaceous diving beetle, water
scavenger beetle, whirligig beetle, carrion beetle stag beetle, June beetle, dung beetle,
Hercules beetle, metallic wood-boring beetle, click beetle, lightningbug, darkling beetle,
blister beetle, long-horned beetle, leaf beetles, bark beetle and snout beetle, plus the life
cycle of the ladybird beetle. 20 slides and guide.

CONTENT SAMPLE: 21069 This jewel-like scarab beetle is a dung beetle (Phanaeus
vindex). Dung beetles are scavengers that feed on animal wastes. They are frequently encount-
ered in pastures, where such material is abundant. A few members of this group are called
tumble bugs because of their habit of rolling dung into a large ball on which the female then
deposits her eggs. The sacred scarab beetle of Egypt is a tumble bug. To the ancient
Egyptians, this beetle’s habit of rolling balls of manure along the ground represented the
rotation of the earth. It became a religious object and many of the ancient religious ceremonies
involved this beetle. Regardless of the supernatural status given to this species, dung beetles
play an important role in sanitation.

REVIEWS: “The selection of the families discussed and the textual material
concerning their natural history is very appropriate.” Previews.

INTRODUCTION TO BUGS, HOPPERS AND APHIDS Order #468........$42.50

Surveys the Hemiptera and Homoptera, illustrates and explains these physically
diverse insects. Includes bed bug, leaf bug, damsel bug, assassin bug, milkweed bug,
leaf-footed bug, stink bug, stilt bug, flat bug, cicada and nymph, leafhopper, treehoppers,
spittlebug, froghopper, planthoppers, whitefly, aphid, woolly apple aphids, scale insects
and mealybugs, plus the life cycle of the boxelder bug. 20 slides and guide.

CONTENT SAMPLE: 21352 Here we see the life cycle of the boxelder bug (Leptocoris
trivittatus). At the top left are its eggs. The shells are transparent and the embryos inside are
responsible for the red color. Those eggs that have already hatched appear transparent.

The newly-hatched, first nymphal instar of the boxelder bug (top right) resembles the
adult bug, but lacks wings and is only about one-tenth the size. After this stage of growth is
complete, the nymph will molt and grow a little larger. Most insects undergo from four to eight
molts before becoming adults.

GRASSHOPPERS, CRICKETS AND MANTIDS Order #469........$42.50

Behavior and anatomy of the Orthoptera. Includes spur-throated, band-winged
and slatfaced grasshoppers; bush katydid; shieldbacked grasshopper; camel,
Jerusalem, field, house, tree and mole crickets; American and wood cockroaches;
California and Mediterranean mantids; plus more. 20 slides and guide.

CONTENT SAMPLE: 21474 This slant-faced grasshopper (subfamily Acridinae) is a
less often encountered member of the short-horned grasshopper family. These grasshoppers
are so-named because of their strongly slanting faces, a characteristic which distinguishes them
from most other short-horned grasshoppers. These grasshoppers stridulate by rubbing a row of
small pegs on their hind femora against a thickened vein on each front wing. This produces a
soft, rasping noise.

Slant-faced grasshoppers are found in moist areas, such as wet meadows and marshes,
but they are not as common as the band-winged and spur-throated grasshoppers. The antennae
are often somewhat flattened and the wings may or may not be fully developed in the adults.

REVIEWS: “An excellent series of slides.” Previews.

INTRODUCTION TO FLIES Order #470........$42.50

Introduces Diptera, one of the largest orders of insects and of special
significance to man. Explains their importance and behavior. Includes crane flies
leatherjacket, midge bloodworm, gall gnats, black fly, horsefly, deer fly, robberfly, long-
legged fly, bee fly, syrphid fly, fruit fly, vinegar flies, house fly, stable fly, flesh fly,
tachinid fly, blow fly and maggots, plus the life cycle of Culex. 20 slides and guide.

CONTENT SAMPLE: 21339 This sinister character is a female horsefly (genus
Tabanus, family Tabanidae). Horse flies are large to medium size flies with some species
reaching 25 mm (1 in.) or more in length. These creatures are competent fliers and many are able
to overtake a fast-running horse. The females are vicious biters, often attacking livestock. An
animal may lose as much as three ounces of blood per day when these females are present in
large numbers. A number of species also do not hesitate to attack man.

Male horse flies do not bite. They are often found on flowers where they feed on nectar
and pollen. The females are also known to feed on plant juices when animal blood is not
available.
