A Study of Spiders (Araneae) on Maple Trees (Acer Spp.) [PDF]

open access: yes, 2017
We began this study to determine whether spider species occur randomly on maple species or whether they are selective in picking either their host species or their position on that host.

Attack on Titan: a record of predation on the Chinese reddish mantis Hierodula chinensis (Mantodea, Mantidae) by the orb-web weaving spider Gibbaranea abscissa (Araneae, Araneidae) [PDF]

open access: yesJournal of Orthoptera Research
Prey–predator interaction is a phenomenon important to our understanding of community dynamics. Mantises and web-weaving spiders are predators that belong to the same guild, and they can be each other’s predator and prey.

Bat predation by spiders. [PDF]

open access: yesPLoS ONE, 2013
In this paper more than 50 incidences of bats being captured by spiders are reviewed. Bat-catching spiders have been reported from virtually every continent with the exception of Antarctica (≈ 90% of the incidences occurring in the warmer areas of the ...

Behavior and Bioadhesives: How Bolas Spiders, Mastophora hutchinsoni, Catch Moths

open access: yesInsects, 2022
Spiders use various combinations of silks, adhesives, and behaviors to ensnare and trap prey. A common but difficult to catch prey in most spider habitats are moths.

Second-order Nonlinear Optical Microscopy of Spider Silk [PDF]

open access: yes, 2017
Asymmetric $\rm \beta$-sheet protein structures in spider silk should induce nonlinear optical interaction such as second harmonic generation (SHG) which is experimentally observed for a radial line and dragline spider silk by using an imaging ...

The northernmost record of Eriostethus rufus (Uchida, 1932) (Hymenoptera, Ichneumonidae) with an indication of new host, Trichonephila clavata (Koch, 1878) (Araneae, Araneidae) and its web manipulation

open access: yesEntomological Communications, 2021
Eriostethus rufus (Uchida, 1932) is a polysphinctine ectoparasitoid of araneid spiders (Neoscona spp.) and is endemic to Japan. An individual was collected in Yamagata Prefecture (38º46' N), northern Japan, the northernmost record of the species and also

Consequences of electrical conductivity in an orb spider's capture web

open access: yesNaturwissenschaften, 2013
The glue-coated and wet capture spiral of the orb web of the garden cross spider Araneus diadematus is suspended between the dry silk radial and web frame threads. Here, we experimentally demonstrate that the capture spiral is electrically conductive because of necks of liquid connecting the droplets even if the thread is stretched. We examine how this

An alternative host of Hymenoepimecis japi (Hymenoptera, Ichneumonidae) on a novel family (Araneae, Araneidae), with notes on behavioral manipulations

open access: yesJournal of Hymenoptera Research, 2017
Polysphinctine wasps of the genus Hymenoepimecis act as koinobiont ectoparasitoids of orb-weaver spiders. Hymenoepimecis japi is already known to parasitize the tetragnathid spider Leucauge roseosignata.

Spiders in a hostile world (Arachnoidea, Araneae) [PDF]

open access: yes, 2011
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders.
