The image shows a garden spider feeding on a common wasp caught in its web.
In laboratory spider feeding trials, mayfly DNA could be detected up to 192 h post-ingestion; however, we detected no mayfly predation in a sample of 110 wolf spiders collected at the site during mayfly emergence.
Some female spiders feed their young.
Finally, spiders fed late in the experiment did not reproduce, even though they received the same amount of food as spiders fed earlier, 43% of which reproduced.
Three thousand meters below the ocean's surface, a remotely operated vehicle has captured never-before seen images of deep-sea spiders feeding in their natural habitat.
The spiders fed on live flies built larger webs with more radii that were less stiff and had greater vibration damping.
The spiders fed in cycles of two to four minutes, then groomed, especially their chelicerae, before another cycle.
The spiders fed in cycles of two to four minutes, then groomed their bodies and especially their chelicerae, before another cycle.
On the contrary, the per capita extracted prey mass decreased with increasing group size: single spiders fed significantly more efficiently than groups of three and six spiders.
Hence, in groups of 6 spiders, on average three spiders shared a prey (3.3 ± 0.21 spiders feeding, n = 20), while in groups of 3 spiders mostly two or one spider fed (mean ± SD: 1.6 ± 0.16 spiders feeding, n = 22, One-factorial test: χ2 = 19.76, DF = 1, p ≤ 0.0001).
