Coxal gland

The gland consists of an end sac (saccule), a long duct (labyrinth) and a terminal bladder (reservoir).

[2] There is generally only one pair (two in some spiders), and they open on the coxae of the walking legs[1] or at the base of the second antennae in the case of the crustacean antennal gland.

They were discovered microscopically and named by André Lopez for the first time in Metepeira and later on in other genera (1978,1983,1984)(external link "archentoflor") The excretory system of the prawn lacks a true kidney.

The following parts are found in its excretory system:[3] In invertebrates with coxal glands, many forms of communication are conveyed via chemicals in the urine.

Neonicotinoids are widely used systemic insecticides that act as a neurotoxin to most arthropods that are water soluble and frequently make it into various waterways.
