I report herein an observational case that Argiope amoena, a common large orb-weaving spider representative in Japan, preyed on a yellow-vented hornet Vespa analis insularis with wrapping. It was previously reported that about half of the diets foraged by A. amoena are composed of Hymenoptera mainly honeybees and ants (Formicidae gen. sp.). However, to my knowledge, the cases that a hornet of Vespa sp., the largest of the eusocial wasps and known as a predator of insects and spiders, is fed upon by A. amoena, are rarely documented in scientific literature; by contrast, some cases, vespine hornets attack Argiope spiders and steal the prey items from the web of argiopids, have been reported. The present study shows that A. amoena is not only a prey fed upon by the vespid but also one of the natural enemies of the yellow jacket such as V. analis.

In the present study, I reported that the female adult crab spider Thomisus labefactus preyed on a female adult of the wasp spider Argiope bruennichi in the centre of the web. To my knowledge, the case that a large orb-weaving spider A. bruennichi is fed upon by the crab spiders with web-invading is not known previously. It has been shown that T. labefactus, considered commonly as a sit-and-wait predator, also aggressively hunt A. bruennichi, the large web-building spider, attacking its prey at the centre of web.
