The eyes of male and female Rhagophthalmus ohbai are of very different sizes and possess approximately 3000 and 35 facets, respectively. In the male eye one can distinguish a smaller dorsal region with 500 facets and a larger ventral one with ca. 1800. Ultrastructural differences between them have been described earlier in this journal (Lau and Meyer- Rochow, 2006). Electrophysiological recordings from the two eye areas have now revealed that the ventral region is maximally sensitive to light of 600 nm wavelength, while the dorsal eye region responds maximally to light of 540-560 nm wavelengths. In the dorsal eye region sensitivity to UV-radiation at around 360 nm wavelength, being twice as high as that of the ventral eye region, amounted to ca. one quarter of peak wavelength sensitivity. The regional differences in spectral sensitivity seem to be a reflection of the different tasks of the two eye regions: looking downward to see the yellow light emitted by a female, sensitivity towards longer wavelengths would be advantageous, but looking upward into the twilight sky, sensitivity to shorter wavelength would be a more appropriate adaptation.

Background: References to insects in myths, stories, and idioms can be found in almost any culture, but with regard to references involving honey bee species in the Asia-Australian region, little information is available. Such references to bees can be highly informative by revealing attitudes of admiration, fear, ignorance, or even revulsion towards these insects. Results: The subject is briefly reviewed and examples of references to bees of selected cultural communities are given. Although folkloristic references to honey bees were found to be mostly positive highlighting fearlessness, cleverness, and industriousness of the bees, some also touch upon their ability to cause pain. Conclusions: Owing to the decreasing contacts and increasing alienization regarding insects generally, a plea is made to collect whatever information is still available about references to bees in songs, myths, stories, proverbs, and idioms and to compare such uses from different regions, e.g., North and South Korea. This would support other fields of research aiming to discover and to describe cultural relationships, migrations, and contacts between different peoples of the Asian/Australian region.

The lepidopteran family of the Epipyropidae contains currently 32 known species of moths with larvae that are parasitic on plant and leafhoppers as well as cicadas. This paper focuses on behavioural aspects of the final instar of the cicada parasite Epipomponia nawai (Dyer 1904) on the cicada Hyalessa maculaticollis (de Motschulsky 1866) and represents only the second report of the species from South Korea. This species is a new host for E. nawai in Korea, since in the past it had only been reported once from Meimuna opalifera and Oncotympana fuscata in Korea. Molecular relationships between specimens of E. nawai collected in China, Japan, and Korea were analysed. The Chinese haplotypes fell into two groups: one clearly related to the Korean haplotype, but the other tightly affiliated with the Japanese haplotype. The findings suggest two routes for the occurrence of E. nawai in mainland China. Once the host cicada was dead or too weak to move, the caterpillar crawled away from it, seeking a place to pupate. Very little is known about parasitic Lepidoptera and therefore any information on host species or behavioural aspects is of importance.

Insects and their uses in a cold country: Finland
Victor Benno MEYER-ROCHOW 한국곤충학회 2008 Entomological Research Vol.38 No.-
Northern European countries, despite their geographic location and climatic conditions, have a considerable number of insect species. To date 20 532 species of insects are known from Finland. Honeybees were introduced to Finland in the 18th century. The total number of hives in the country today is 50 000, with each producing an annual 30–40 kg of honey. A considerable amount of research is carried out on bees in Finland by beekeepers and scientists and the Finnish Beekeeper Association publishes its own journal by the name of Mehiläinen for approximately 3300 subscribers. Insects also play important roles in the education and school curricula of Finnish children with insect boxes containing preserved specimens, identification keys and information on general biology available for classes. Some butterflies get framed and hung on walls, serving as room decorations. Insects also feature as motifs on Finnish t-shirts. Forensic entomology was pioneered in Finland and numerous university departments (zoology, entomology, ecology, physiology, biophysics, pharmacology and genetics) as well as museums are engaged in research on insects. Monitoring climate change, insects in Finland (especially Lepidoptera) are highly suitable because of the many years of recorded distributions and abundances of species. Finally, the large amount of idioms in the Finnish language, making reference to insects, testifies to the intimate connection between the Finnish people and the insects of their country.

Out of 26 students (11 male, 15 female) that were blindfolded and held their noses, 14 correctly identified the taste of insects when given pieces of cheese, dried fish, beondaegi (commercially available Korean Bombyx mori silkworm pupae), inago (commercially available Japanese Oxya yezoensis grasshoppers) and white bread to taste. Eight identified one of the food insects and four failed to detect any. Of 11 students given a choice between beondaegi, inago and hachinoko (larval wasps of Vespula flaviceps) most students preferred the inago grasshoppers, three ranked the commercially available hachinoko first and one gave the top position to the beondaegi silkworm pupae. It is concluded that insects, per se, are not terribly easy to identify by taste alone. Given the well documented aversion of especially people of western cultural backgrounds to insects in food, our results suggest that insects processed into flour or pastes have a greater chance to be accepted by the consumer (as they cannot easily be identified by taste alone) than food that displays insect images on its packing. Highlights: For the first time taste tests were carried out to determine whether blindfolded participants who were unable to smell could identify edible insects by taste alone. 46% failed.
