Araneus Araneus Araneus is a genus of common orb-weaving spiders. It includes about 650 species, among which are the European garden spider and the barn spider. Spiders of this genus present perhaps the most obvious case of sexual dimorphism among all of the orb-weaver family, with males being normally to the size of females. In "A. diadematus", for example, last molt females can reach the body size of up to 1 in (2.5 cm), while most males seldom grow over 0.3 in (1 cm), both excluding legspan. Males are differentiated from females by a much smaller and more elongated abdomen, longer
Black garden ant Black garden ant The black garden ant ("Lasius niger"), also known as the common black ant, is a formicine ant, the type species of the subgenus "Lasius", found all over Europe and in some parts of North America, South America, Australia, Asia and Australasia. The European species was split into two species; "L. niger" is found in open areas, while "L. platythorax" is found in forest habitats. It is monogynous, meaning colonies have a single queen. "Lasius niger" colonies can reach in size up to around 40,000 workers in rare cases but 4,000–7,000 is around average. A "Lasius niger" queen
