Tenthredinidae
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis. The family has no easily seen diagnostic features, though the combination of five to nine antennal flagellomeres plus a clear separation of the first abdominal tergum from the metapleuron can reliably separate them. These sawflies are often black or brown, and 3 to 20 mm long. Like other sawflies, they lack the slender "wasp-waist", or petiole, between the thorax and abdomen, characteristic of many hymenopterans. The mesosoma and the metasoma are instead broadly joined. The Tenthredinidae are also often somewhat dorsoventrally flattened, which will distinguish them ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ...
