Spider are apparently absent. In some species, the exocuticle of the legs and prosoma is modified by a tanning process, resulting in brown coloration. Bilins are found, for example, in "Micrommata virescens", resulting in its green color. Guanine is responsible for the white markings of the European garden spider "Araneus diadematus". It is in many species accumulated in specialized cells called guanocytes. In genera such as "Tetragnatha", "Leucauge", "Argyrodes" or "Theridiosoma", guanine creates their silvery appearance. While guanine is originally an end-product of protein metabolism, its excretion can be blocked in spiders, leading to an increase in its storage. Structural colors

He commissioned the Jesuit priest Father Castiglione, who was trained in engineering, to build fountains for his garden similar to those he had heard about in the gardens at Versailles. Chinese architecture and aesthetics also influenced the English garden. In 1685, the English diplomat and writer Sir William Temple wrote an essay "Upon the garden of Epicurus" (published in 1692), which contrasted European theories of symmetrical gardens with asymmetrical compositions from China.
