Deloyala Guttata
''Deloyala guttata'', the mottled tortoise beetle, is a species of tortoise beetle in the family Chrysomelidae. It is found in the Caribbean, Central America, North America, and South America. Larva carry shields made from exuviae and frass Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the ... on their abdomen that they lift to shield their dorsum from predators. References Further reading * Arnett, R. H. Jr., M. C. Thomas, P. E. Skelley and J. H. Frank. (eds.).

Guillaume-Antoine Olivier
Guillaume-Antoine Olivier (; 19 January 1756, Les Arcs near Toulon – 1 October 1814, Lyon) was a French entomologist and naturalist. Life Olivier studied medicine in Montpellier, where he became good friends with Pierre Marie Auguste Broussonet. With Jean Guillaume Bruguière and Jean-Baptiste Lamarck . Jean-Baptiste-François Gigot d'Orcy later employed Olivier who was then able to travel to England and Holland meeting Thomas Martyn in London. In 1789 and 1790 he published the first two volumes of the ''Histoire naturelle des Coléoptères'' for Gigot d'Orcy, and simultaneously, thanks to Daubenton's recommendation, collaborated in the ''Dictionnaire de l'Histoire naturelle des Insectes, Papillons, Crustacés'' and collaborated in the creation of ''Journal d'Histoire Naturelle'' (1792). Afterwards, he served as a naturalist on a 6-year scientific journey that took him to Asia Minor, Persia, Egypt, Cyprus and Corfu. He returned to France in 1798 with a large collecti ...

Chrysomelidae
The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Members of former chrysomelid subfamilies ( Orsodacnidae and Megalopodidae) are also difficult to differentiate from true chrysomelids. Adult and larval leaf beetles feed o ...

Exuvia
In biology, exuviae are the remains of an exoskeleton and related structures that are left after ecdysozoans (including insects, crustaceans and arachnids) have molted. The exuviae of an animal can be important to biologists as they can often be used to identify the species of the animal and even its sex. As studying insects, crustaceans, or arachnids directly is not always possible, and because exuviae can be collected fairly easily, they can play an important part in helping to determine some general aspects of a species' overall life cycle such as distribution, sex ratio, production, and proof of breeding in a habitat. Exuviae have been suggested as a "gold standard" for insect monitoring. For instance, when monitoring dragonfly populations, the presence of exuviae of a species demonstrates that the species has completed its full life cycle from egg to adult in a habitat. However, it has also been suggested that the fact that exuviae can be hard to find could lead to an und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excrement; us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassidinae
The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra. Description The "cassidoids" have a rounded outline with the edges of the pronotum and elytra expanded, spreading out to cover the legs and head. They are often colourful and metallic, with ornate sculpturing; a few species have the ability to change colour due to water movements within the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi. The hispoids have larvae that are ecological diverse as leaf miners or cryptic exophagous feeders, while the cassidoids feed freely externally ...

Beetles Described In 1790
Beetles are insects that form the order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids ...
