The term glomerulonephritis (GN) covers a group of conditions in which there is injury in the glomerulus, the filtering unit of the kidney. This can occur either as a primary glomerular disease, or secondary to drugs, infections or tumours (see Secondary Glomerular Disease, pp 464â466 of this issue).
As insects are spiders' main prey, it is likely that they would impose strong selectional forces on the foraging behavior of spiders. Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them.
Before plunging into the facts as to what do spiders eat let me first briefly explain about this specie. Spiders are the insects that belong to the order of Araneae. They have eight legs and chelicerae coupled with fangs that instill venom. Spiders are air-breathing arthropods with the total number of species counted (in 2008) to 40,000 in the world.
