Figure 1 in Dong et al. (2025): "Fecundity schedules (mean number of spiderlings per female produced in each consecutive egg sac) of female Steatoda grossa spiders fed constantly with late instar cricket nymphs (red boxes) or intermittently with mid instar cricket nymphs (blue boxes). Boxes represent the interquartile range (IQR) of the data with the top and bottom edges of the box indicating the first and third quartiles. Black lines inside boxes represent the median. The whiskers extend from the box to the minimum and maximum values within a certain range, and data points beyond whiskers are considered outliers"

argiope aurantia aka writing #spider and the #eggsac she left behind.
They make a zigzag in the center of their #web so they can use that silk to quickly wrap up their prey.
They can also make their whole web move as an adaptation to scare predators!

Pisaura cf. mirabilis ♀ Pisauridae among the thorns of a wild thistle plant. It's a large spider of no medical relevance to humans, despite its moderate size. It has a dark brown fishbone pattern on the back of its abdomen and a "tuft" of hair on the front of its prosoma.

Copulation interruption decreases female reproductive success in a false widow spider - Behavioral Ecology and Sociobiology Copulation is essential for transferring sperm from males to females in most animals. During copulation, males and females are often static and thus prone to predation or other threats. Its duration s...
