Winter squash is an excellent source of vitamin A, vitamin C, alpha-carotene and beta-carotene. It is also a very good source of thiamin, vitamin B6, potassium, magnesium, and manganese, and a good source of iron.
Spiders are, for the most part, such generalist feeders that they kill many useful insects as well as many pest species, however because pest species are by their nature more numerous than beneficial species they are still effective. They are of great value to the environment.
During their evolutionary history, some species of spiders have changed from a nocturnal to a diurnal lifestyle, and the important change in their environment was irradiation by sunlight. Orb webs of diurnal spiders may be markedly affected by exposure to ultraviolet (UV) irradiation, whereas those of nocturnal spiders may be unaffected.
