Know your foe: synanthropic spiders are deterred by semiochemicals of European fire ants

Royal Society Open Science, 2021
Many ants prey on spiders, suggesting that web-building spiders may avoid micro-locations near ant colonies or frequented by foraging ants. Here we tested the hypothesis that ant-derived semiochemicals deter synanthropic spiders.

Evidence of the Most Stretchable Egg Sac Silk Stalk, of the European Spider of the Year Meta menardi [PDF]

, 2011
Spider silks display generally strong mechanical properties, even if differences between species and within the same species can be observed. While many different types of silks have been tested, the mechanical properties of stalks of silk taken from the
