Introduction to the Myriapoda They've got legs. . . they know how to use them. . . Click on either of these images to view an enlarged version! Nearly 13,000 species of arthropod are classified in the Myriapoda, the "many-legged ones." All myriapods are terrestrial forms. Like insects and other uniramian arthropods, myriapods have appendages with only one branch, or ramus . Myriapods can have anywhere from fewer than ten to nearly 200 pairs of appendages; they range in size from nearly microscopic to 30 cm in length. Most myriapods live in humid environments, and can be found in soils, in leaf litters, or under stones and wood. Many species possess repugnatorial glands , specialized glands that secrete foul-tasing compounds and thus function in defense. There are four groups of myriapods; how they are related to each other is not yet well understood. Two of them, the Symphyla and Pauropoda , consist of tiny arthropods living in leaf litter and soil; both superficially resemble centipedes. The Chilopoda includes the true centipedes, like the one shown at the top left of this page. Chilopods have only one pair of legs per body segment. They are predators; the first pair of appendages on the trunk are modified into a pair of claws with poison glands, which centipedes use to capture prey (usually other arthropods). The bite of large centipedes can cause humans some pain and discomfort, although there are no authenticated cases of human fatalities from centipede bites.

Eurypterids are now extinct; they lived 200 to 500 million years ago. Some were huge, reaching a length of 3 m. Their morphology suggests that they fed on a variety of kinds of foods. Some may have been amphibious, emerging onto land for at least part of their life cycle. The horseshoe crabs are an ancient group, but only 5 species exist today. They feed on small invertebrates. Horseshoe crabs are often used as laboratory animals by physiologists. Members of this class have a large shield that covers the cephalothorax. The compound eyes are reduced. The second pair of appendages, the pedipalps, resemble walking legs. They have a long, spike-like appendage called a telson that projects from the rear of their bodies. Respiration is via book gills.

Introduction to Branchiopoda Sea monkeys, tadpole shrimp, water fleas, and clam shrimp Left: A mirrored right lateral view of Daphnia magna , courtesy of www.splash.org Right: A right lateral view of a fairy shrimp, courtesy of U.S. Fish and Wildlife Service The Branchiopoda consist of four living groups: the Anostraca ("fairy shrimp" or "sea monkeys"), Notostraca ("tadpole shrimp"), Cladocera ("water fleas"), and Conchostraca ("clam shrimp'). There are also two fossil groups that belong to the Branchiopoda, but it is unresolved whether they are subgroups within the living groups or evolved separately. Here the fossil groups will be discussed within the living groups to which they are most similar. With almost 800 described species, it is difficult to generalize about the branchipods. Most live in fresh or brackish (slightly salty) water and a few are found in marine habitats. Many are found exclusively in temporary ponds, where their eggs survive long periods of drought. You often find packages of dried eggs for sale in pet and toy stores. When the eggs are placed in water with an airstone, they hatch in just a couple days and you can watch them grow and swim. They are often used as food for aquarium animals. It is even more difficult to generalize about the body form of branchiopods. The thorax and abdomen are fused or indistinguishable in most but the Anostraca. Their

They are found world-wide except for in extremely cold regions such as Antarctica, northern Canada and Asia, and Iceland. There are three sub-orders in the Odonata: the Anisoptera , whose hind and fore wings are a different shape; Zygoptera or "damselflies", who are small and delicate and with both the fore- and hind wings being the same size; and the Anisozygoptera , which resemble the Anisoptera, but share similar characteristics between both the Zygoptera and Anisoptera sub-orders. There are about 5,000 species of odonates. Species included in the Animal Diversity Web: Suborder Anisoptera MORPHOLOGY The Head: The head consists of six segments that contain different structures: First segment -compound eyes Second segment -antennae (consists of three to seven joints) Third segment-none Fourth segment-mandibles (teeth are extremely strong) Fifth segment- first maxillae (jointed appendages not as strong as those of the mandible) Sixth segment-second maxillae The Thorax: The thorax of the dragonfly is highly specialized to meet the requirements of supporting powerful wings and the altered functions of the legs. There are three pairs of legs, one connected to each thoracic segment. Though the legs are short, they are of considerable strength and are covered with tiny spines.

53. Introduction To The Siphonaptera A brief introduction to fleas by UCMP Berkeley, with photograph. http://www.ucmp.berkeley.edu/arthropoda/uniramia/siphonaptera.html

Siphonaptera Fleas Ctenocephalides felis , the cat flea shown here, is a typical member of the Siphonaptera ("sucking-wingless"), the fleas. Although known to be related to the true flies (the Diptera ) by details of internal structure, the Siphonaptera are highly modified for a parasitic existence; they have no wings and no compound eyes, the legs are modified for jumping, the antennae are very short and recessed in grooves on the head, and the body is highly flattened laterally. Most are parasites on mammals ; a few live on birds . Adult fleas feed on blood, while their larvae feed on organic debris. Fleas are extremely rare as fossils; their small size and specialized habitat makes them highly unlikely candidates for fossilization. Two species have been found in amber from the Baltic region (late Eocene-Oligocene); living members of the family of fleas to which these fossils belong ( Hystrichopsyllidae ) are mostly parasitic on insectivores (moles and shrews). A few Cretaceous fossils have been assigned to the Siphonaptera (e.g. Riek, 1970), but some of these fossils are questionable (Carpenter, 1992). Since the Siphonaptera are mostly parasitic on mammals, they presumably evolved at about the time the mammals were evolving, in the Jurassic and Cretaceous.

54. Introduction To The Hymenoptera This resource for eusocial insects is small but detailed. UC Berkeley, updated regularly. http://www.ucmp.berkeley.edu/arthropoda/uniramia/hymenoptera.html

Hymenoptera Bees, ants, and wasps Hymenopterans, the "membrane-winged" insects , include bees, ants, and a large number of other insect taxa collectively referred to as wasps. The Hymenoptera include famous examples of social insects, such as honeybees and true ants; these insects have developed regimented social systems in which members are divided into worker, drone, and queen castes. Such social hymenoptera may live together in nests or hives of many thousands of individuals, all descended form a single queen. Not all hymenoptera are social, however; many live a solitary life, coming together only for a brief mating. As is obvious from the picture above, hymenopterans include important pollinators of flowering plants . Flowers pollinated by bees are typically yellow or blue and often have patterns visible only under ultraviolet light, which bees can see. Many bee-pollinated flowers are bilaterally symmetrical and produce abundant nectar, such as the orchids , some species of which depend on a single species of bee for pollination. Other plants may be pollinated by ants, or may rely on ants living within them to keep predators away. Many of these plants produce large quantities of nectar, or produce other fluids for the ants. Less well-known, but equally spectacular, are the various families of parasitoid wasps;

Information on the Internet Introduction The first fossil Orthoptera appear in the upper Carboniferous with the first Ensifera (Chopard 1920) appearing in the Permian and the first Caelifera (Ander 1939) in the Triassic (Gorochov 1995; Kukalova-Peck 1991; Sharov 1968; Zeuner 1939). The two groups are usually considered suborders of the Orthoptera. Attempts to create a separate order for the two suborders Caelifera and Ensifera (e.g. Kevan 1986, in which Ensifera = Grylloptera) have not found general entomological acceptance (see Discussion of Phylogenetic Relationships). Characteristics The name Orthoptera is derived from "orthos" meaning "straight" and "pteron" = "wing." Shared-derived characters: in addition to the saltatory hind legs, most orthopterans have small and well separated hind coxae, a pronotum with large descending lateral lobes, nymphal wing rudiments reversing their orientation in later instars and hind tibiae with two dorsal teeth rows (Kevan 1982; Kukalova-Peck 1991; Rentz 1991). Other characteristics are unsegmented cerci and leathery forewings.

Harris Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Lepidoptera Members of this Order What makes a butterfly a butterfly? In common with many other insects, adult butterflies have antennae, compound eyes, three pairs of legs, a hard exoskeleton, and a body that is divided into three parts: the head, thorax, and the abdomen. Uniquely, a butterfly's outer body is covered by tiny sensory hairs and the wings are covered by scales. The head carries many sensory apparati for the butterfly. A butterfly's compound eye enables it to be aware of its immediate surroundings through a large angle. The pair of are clubbed in most butterflies. On the underside of the head is the paired proboscis, which is used to suck nectar from flowers. The thorax consists of three segments with a pair of legs attached to each segment. The front pair of legs are non-functional and reduced in length in some families of butterflies. The thorax also contains the flight muscles, which are attached to the base of the wings. Internally, the thorax houses the large muscles that control the wings and legs.
