Warm summers in the forests of Kamchatka triggered abnormal growth of the number of spiders that alarmed mushroom and berry bushes, reports Kronotsky Reserve.
"Mushroom and berry lovers are concerned about the number of abnormal spider Kamchatka flooded forest. Mushroom collectors, but have nothing to fear, all spiders are not poisonous and will disappear with the coming of autumn cold. Reason for increasing the number of arthropods — a stable warm weather. Nature finds itself justice on their creations: recent years favorable for the development of small insects and spiders eat them, serving as a pest control "- says entomologist Kronotsky reserve Lyudmila Lobkova.
Residents of the region are also concerned about the situation with the mites that are relatives of spiders. However, experts hasten to reassure the population: expedition of the Moscow Institute of Virology and Epidemiology showed that carriers of tick encephalitis in Kamchatka not.
Thus predict the number of spiders in the following summer, scientists still can not: spider offspring survival depends on the severity of the coming winter. The life of spiders is relatively short — fall female twist around web cocoon laying of hundreds of eggs and dies. In the spring of the clutch, a new generation of spiders.
