HYMENOPTERA, TENTHREDINIDAE

Common name. Sawflies

Tenthredo sp.

Sawflies make up the suborder Symphyta, a group of largely phytophagous insects in the order Hymenoptera.
This group is an artificial assemblage of superfamilies, but the name is still in common use, and treated as a suborder, though it seems likely it will be phased out in future classifications.
These superfamilies are essentially the most primitive taxa within the Hymenoptera.
Sawflies are distinguishable from most other Hymenoptera by the broad connection between the abdomen and the thorax, and the caterpillar-like larvae.
The common name comes from the appearance of the ovipositor, which looks much like the blade of a saw. This ovipositor, which is modified into a "sting" in some members of the Apocrita, is not used as a weapon. Females use the ovipositor to cut into plants where they lay their eggs. A few species have long thin ovipositors used to drill holes deep into wood.
Adult sawflies have structures that latch onto the underside of the forewings to help hold the wings in place when the insect is at rest. Adults of some species are carnivorous, eating other insects, but many also feed on nectar.

The Tenthredinidae is the largest family of sawflies, with well over 6000 species worldwide. The family has no easily-seen diagnostic features. These sawflies are often black or brown, and from 3-20 mm long. Like other sawflies they lack the slender "waist," or pedicel, between the thorax and abdomen, which are instead broadly joined. They have long threadlike antennae composed of 7-10 segments, and are often clubbed or comblike.

Tenthredo is a genus of family Tenthredinidae with well over 100 species in Europe.

Ciao Marcello foto decisamente più "pulita" nel soggetto rispetto a quella di ieri, la perfezione non è di questo mondo, ma le tue macro rappresentano quanto di meglio si può fare con una macchina fotografica e le tue note sono sempre all'altezza, al solito, Bravissimo, buon week end, ciao Silvio

Hi Marcello,
Outstanding close-up shot of this Sawfly with immaculate sharpness and details. The pink flower does present a fine BG and adds colour to the frame. Good use of natural light and a precise DOF. Excellent POV and composition. Kudos.
TFS.
