Linyphia triagularis

| [Note Guidelines] Photographer's Note |
After I bought the 105mm Macro I needed some lightning. I sold my SB600 and got my self a SB800 that is able to dive -7°. This was one of my first try.
As the season advanced, Agelena spiders disappeared from the bushes in front of my office and a population of linyphia triangularis appeared. I’m not sure at all so if someone could please confirm.

The picture shows an adult female of Linyphia triangularis. It has an annual life cycle in Sweden, overwintering as eggs in a cocoon. The cocoon, or egg sac, is placed below twigs or under dead leaves on the ground. The egg hatches around the beginning of April and the spiders grow during the summer to reach maturity in the end of July - beginning of August. The males abandon their webs after maturing and search for unmated females. Males mature about a week before females so unmated females are usually equivalent to subadult females. The males guard an unmated female until she matures and he can mate with her. During this time he has to defend her from other males that finds her web and fights betwen males can lea to serious injury or death for the loser. The female accepts to mate with the male guarding her as soon as she has matured. After the complicated courtship and copulation that lasts for several hours, the male deposits a mating plug in her reproductive opening and leaves searching for other females to guard. Sheet-web spiders are generally believed to have a "first-mate priority system", which means that the first male to deposit sperm in the female's spermatheca also fertilises most or all of the eggs of that female. ?In spite of the 5 - 10 % shorter development time available, the male of this species grows to a size about 10 - 15 % larger than the female. This paradoxical relationship is unique among web-building spiders. |
