Adult female Nephila clavata (Araneae: Nephilidae), orb-weaving spiders, captured stink bugs Plautia stali without rolling with thread, though N. clavata usually roll their preys with thread. Stink bugs defense themwith unfavored odor. The reason why N. clavata preyed on the stink bugs without winding them might be to make volatilize. Nephila edulis put decaying matters such as dead preys and leaves on their barrier web with attracting prey insects by odor, in addition N. clavipes put the dead stink bugs to attract flies. N. clavata put the stink bugs on their web after feeding, indicating that N. clavata could attract preys such as flies.

A female Atypus karschii (25 mm long including chelicerae) was collected on the street in front of the Faculty of Education, Nagasaki University on July 16, 2019. From the chelicerae of it secreted colorless liquid that appeared to be a venom. Pyrolysis-GC/MS measurement revealed that the secreted liquid contained some components such as aliphatic and aromatic compounds. In addition, a burrow of Calommata signata (Araneae: Atypidae; Near Threatened) was also found nearby.

I report herein that the cases of fly, stilt bug, and ant in web of two spiders, long-jawed orbweaver Leucauge blanda (Araneae: Tetragnathidae) and trashline orbweaver Cyclosa sp. (Araneae: Araneidae). Insects those were supposed to be Sepsis monostigma (Diptera: Sepsidae) were captured in the web of L. blanda. On another web of L. blanda, an insect that was supposed to be Yemma exilis (Heteroptera: Berytidae) stayed. An ant supposed to be Paratrechina longicornis (Hymenoptera: Formicidae) was found in a detritus stabilimentum of Cyclosa sp.
