Morphology of dragonflies

Sequences of rRNA will be aligned manually utilizing secondary structure models Gutell et. The first Odonata Morphology of dragonflies were found in sediments from the Lower Permianover million years old. Emergence occurs quickly at the water surface as the pupal skin breaks to liberate the adult.

Herbaceous and woody plants are both attacked, but larvae tend to feed on a single host plant, or a narrow spectrum as host plants as leaf miners, stem borers, or seed-head predators.

Introduction to the Odonata

The adults are also known as blue bottle and green bottle flies because some taxa have metallic brightly colored bodies Figs. The electron gun is the cylindrical part sticking up above the sample chamber.

Larvae frequently infest cheese and exhibit the rather peculiar escape strategy of grabbing the posterior body segment with their mouthhooks to form a U shape and then releasing their grip, which causes the larvae to propel, or skip, away from their original location.

It also bears the mouthparts. The experience is painful, and most infected travelers have the larva removed surgically prior to pupariation or adult emergence. For example, in dragonflies and damselfliesit is between the compound eyes, clypeus, and mouthparts.

The exterior of the nematoceran pupa may be adorned with spines, gill-like respiratory devices, or locomo-tory paddles Figs.

Fruit fly species are also specific in the area of a plant that they infest. Some species can tolerate a broad range of conditions while others are very sensitive to their environment.

Notice the relatively stout body, and the wings extending to each side while the dragonfly is perched. Adults Dragonfly Morphology Front and hind wings dissimilar in size and shape, the hind wing considerably wider at the base than the fore wing.

However, it is currently a question of debate as to whether members of Protodonata and the earliest Odonata had aquatic larvae, as do all modern species, since no Paleozoic larvae fossils are known.

Insect morphology

They have three ocelli and short antennae. Several other species belong to the bloodsucking muscoid flies and include the tsetse fly of Africa, responsible for transmitting the pathogen causing human sleeping sickness, and the stable fly Muscidae Fig.

Leaf mines are frequently seen as dead or brown areas on a leaf surface, and mine morphology is sometimes distinctive enough to determine which agromyzid species is responsible for plant damage.

Wingless and, therefore, flightless groups include certain tipulids, marine chirono-mids, and phorids, as well as ectoparasitic adults of Hippoboscidae and Nycterobiidae. Many larvae have relatively large, tong-shaped mandibles, presumably suited to aid the parasitic life history.

Impacts I am continuing my collaboration with Drs. Illustrates on detailed maps the distribution of the Danish Tortricoid moths.

In most groups, the base of each maxilla bears a distinct palpus and the apex of the labium is modified into a labellum, which consists of membranous lobes derived from the labial palpi. Where found, the occipital suture is the arched, horseshoe-shaped groove on the back of the head, ending at the posterior of each mandible.

Please note that a few out of print books are listed at the end of the section and in some cases it may be possible to locate copies - please enquire. This is the first fully illustrated guide to all dragonfly and damselfly species of eastern North America--from the rivers of Manitoba to the Florida cypress swamps--and the companion volume to Dennis Paulson's acclaimed field guide to the dragonflies and damselflies of the West.

Comparative morphology of the thorax musculature of adult Anisoptera (Insecta: Odonata): Functional aspects of the flight apparatus Within Pterygota, the Odonata (damsel- and dragonflies) are aerial key predators with outstanding flight skills enabled by their highly derived flight apparatus (Pfau, Even before hatching from the egg, differences in morphology of the egg distinguish dragonflies (Anisoptera) from damselflies (Zygoptera).

Dragonfly eggs are round and about mm long, whereas damselfly eggs are cylindrical and longer, about 1 mm long.

Dragonflies are flying insects of the order Odonata. There are about 5, species of dragonfly. The adults eat other flying insects. Dragonflies have large compound eyes, which is their main sense organ.

They have four strong transparent wings, and a .
