Setae on the foreleg of a mayfly. Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of ...
In most species of bees, the scopa is simply a dense mass of elongated, often branched, hairs (or setae) on the hind leg. When present on the hind legs, the modified hairs are, at a minimum, on the tibia, but some bees also have modified hairs on the femur and/or trochanter.
They may be irregular or align in two or more rows. The number of rows, the number of setae in each row, the size and the thickness are significant. In many groups, the acrostical setae are replaced by setulae or hairs. prescutellar (psc) two acrostical bristles, more developed than the other acrosticals, inserted in front of the scutoscutellar ...
Preening brush: a dense cluster of setae near the ventral tip of the posterior metatarsi; called a preening comb when present as a transverse row of setae. [22] Procurved: Used to describe a structure which is curved in such a way that the outer edges are in front of the central part; [22] opposite recurved
The socket is closed off by the membrane into which the base of the scape is set. However, the antenna does not hang free on the membrane, but pivots on a rigidly sprung projection from the rim of the torulus. That projection on which the antenna pivots is called the antennifer. The whole structure enables the insect to move the antenna as a ...
The program came about as the result of the Inflation Reduction Act, which included $15 million in funding to study the creation of a website allowing Americans to directly file their taxes to the ...
Setae can range in length from a few micrometers to several millimeters. [6] Dipteran outgrowths are acanthae, which are single sclerotized protuberances originating from a single cell. [ 6 ] The acanthae are hollow inside, and some have pores under the terminal plate, which presumably deliver an adhesive secretion directly to the contact area ...
The economy enters 2025 in reasonably good shape, with a low unemployment rate, modest inflation, a trend toward declining interest rates and strong corporate profit growth that has been giving ...
