Generating checklists could provide new insights into the teaching strategies. Thus, the crystal struc-tures’ data of organic compounds learned in secondary chemical education were collected from the Cambridge Crystallographic Data Centre (CCDC) database. It has revealed that almost all the crystal data of these organic molecules are available, contrarily to an anticipation that liquid or gaseous ones at room temperature have few data. This index data would be fundamental for further studies hereafter.

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.

The wasp spider Argiope bruennichi is a generalist predator. However, cases that A. bruennichi preyed on hornets (Vespa spp.) have been rarely known. On the contrary, the hornet is one of the natural enemies of the wasp spider. In the present study, observation of an unusual case regarding the consumption of a yellow-vented hornet Vespa analis insularis by A. bruennichi with wrapping is reported. The finding could provide a new insight into the predator-prey relationship between orb-web spiders and hornets.

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.

Ultraviolet-visible (UV-Vis) reflectance spectroscopy is one of the useful tools to evaluate the coloration of materials and living things. On crab spiders, sit-and-wait foragers on flowers, body coloration has been focused in the context of camouflage and/or prey attraction. For the first time, the present study shows UV-Vis reflectance spectra of Thomisus labefactus, a crab spider inhabits East Asia, reflects UV-Vis rays almost the same strength as an Australian crab spider Thomisus spectabilis, which also has substantial amount of UV reflection, unlike European species lacking UV reflection.紫外・可視(UV-Vis)反射分光法は,材料や生物の色彩を評価する有益なツールの一つである.カニグモは花の上で獲物を待ち伏せする捕食者であり,擬態および/あるいは餌誘引における文脈で,体の色彩に焦点が当てられてきた.本研究では,東アジアに生息するカニグモ科の一種であるアズチグモThomisus labefactus では最初となるUV-Vis 反射スペクトルの測定から,紫外線反射を欠いているヨーロッパ産の種とは異なり,相当量の紫外線を反射するオーストラリア産のカニグモ科の一種Thomisus spectabilis と同程度の強さで紫外線と可視光を反射することが示される.
