Fossil body parts of the two cold-adapted ground beetle species, Elaphrus lapponicus and Diacheila polita, were found from a deposit dated in the late Last Glacial period in Hokkaido, Japan. The paleoenvironment was estimated from their modern distribution and habitat, along with the results of the paleobotanical studies at the site. The temperatur...

Adelges ( Cholodkovskya ) viridanus (Cholodkovsky 1896) (Hemiptera: Adelgidae) is found throughout Eurasia where it is understood to be anholocyclic, feeding on species of larch ( Larix ), without host alternation. For the first time, we report this species in North America, outside of its native range, from specimens collected in an arboretum in O...

401 papers on Ⅰ. Adelgids and hemlock trees Ⅱ. Cicadas (Cidadidae) Ⅲ. Lady beetles (Coccinellidae) Ⅳ. Mordellidae, Coleoptera Ⅴ. Quaternary Entomology Ⅵ. Other beetles and beetle fauna Ⅶ. Entomological collections Ⅷ. Science education, museology etc.

A citizen survey of the distribution of the three exotic beetles was conducted primarily using the internet. The gradual expansion of Synona consanguinea (Coccinellidae) was recorded in areas surrounding Tokyo and Osaka from 2014 to 2020. The current distribution of Trachymela sloanei (Chrysomellidae) in three megalopolis and Laccoptera quadrifolia...

The distribution of cicada species, Tanna japonensis Distant (Japanese name: Higurashi) , which sings characteristically in summer at dawn and sunset, was surveyed throughout Osaka Prefecture as a citizen research project. Observations were made primarily at religious facilities, or "Jinja" and presence or absence of the cicada was recorded. In mou...

he population localities of the cicada species, Euterpnosia chibensis chibensis（Matsumura, 1917） in the Kinki district are evaluated including previously available records. This species occurs within many localities in the southern regions of both the Kii Peninsula and Awaji Island, and the western and northern regions of Hyogo Prefecture. In oth...

Through examination of the museum collection, literature citation, and field surveys conducted by citizen scientists, 867 species of beetles were recorded in Osaka City. Of them, 195 species are considered to be candidates for Red List, and many disappeared in the 1950s and the 1980s. The number of beetle species is currently highest in the area al...

Thirteen sorts of galls are formed by 8 adelgid species on the 6 species of Picea which are native to Japan. Gall morphology is varied, and multiple species of adelgids can form galls on one Picea tree species. Conversely, one species of adelgid can form galls on multiple Picea tree species. The identification of Picea is simplified when using the...

There have been no rigorous molecular studies of the Asian Platypleurini cicadas to date. We propose that their history was strongly influenced by Quaternary vicariance. Phylogenetic trees of Platypleura cicadas in the Ryukyu islands and neighbours were reconstructed based on the mitochondrial cytochrome c oxidase subunit 1 (COI) gene (1412 bp), th...

Hemlock woolly adelgid, Adelges tsugae, is an invasive pest of hemlock trees (Tsuga) in eastern North America. We used 14 microsatellites and mitochondrial COI sequences to assess its worldwide genetic structure and reconstruct its colonization history. The resulting information about its life cycle, biogeography, and host specialization could help...

The Mutual Climatic Range method of Paleotemperature reconstruction is well suited to Japan, because the meteorological stations are densely located, and the modern distributions of beetles are well studied. Many of the cold adapted species which were in the Japanese lowlands during glacial periods still survive at higher elevations on the Japanese...

A total of 32 species of the family Histeridae distributed in Tottori Prefecture, Honshu, Japan are reported. Eleven of them are new to fauna of the prefecture.

Laricobius osakensis Montgomery & Shiyake, native to Japan, is being measured as a potential biological control agent of the hemlock woolly adelgid, Adelges tsugae Annand, in the eastern United States. Adelges tsugae, a destructive pest threatening the hemlock ecosystems in the eastern United States, was introduced from Japan. This is the first det...

The genus Laricobius (Derodontidae) comprises of twenty-one species in the Holoarctic region. Of which three Laricobius species were recorded from Japan in 2011. Two of them were newly described species. The diagnosis and a key for the three species are provided with records of their distribution and their host plants mainly based on the original p...

Based on the first observation date of calling sounds and the daily mean temperature recorded by the meteorological observatory, adult population fluctuation of a cicada species, Cryptotympana facialis (Walker), for 36 years (1976 – 2011) was estimated in Osaka City. The population of this cicada species increased in the early 1980s, and has retain...

Fossils of Plateumaris weisei (Duvivier) were found from a peat bed of the Last Glacial Maximum in Seri-kawa, Hikone, Shiga Prefecture, Japan. This is its first record from Honshu, the main island of Japan. The fossil record indicates that P. weisei became extinct in Honshu after the Last Glacial Maximum.

Laricobius osakensis Montgomery and Shiyake sp. nov., collected from Adelges tsugae Annand on hemlock [Tsuga sieboldii Carr. and Tsuga diversifolia (Maxim.) Mast.] in Japan, is described and illustrated. The new species was collected from several localities on Honshu, Shikokou, and Kyushu Islands. The genus has not been reported previously from Jap...

Mordellid galls were collected from stems of Japanese mugwort, Artemisia indica var. maximowiczii (Nakai) H. Hara, in early spring at three riverbeds in the Kinki district, central Japan, and reared in the laboratory. Adults of two mordellids, Mordellistena brevilineata Nomura (96.2% of the total number of individuals) and M. fuscosuturalis Nomura...

The hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), is an introduced pest of unknown origin that is causing severe mortality to hemlocks (Tsuga spp.) in eastern North America. Adelgids also occur on other Tsuga species in western North America and East Asia, but these trees are not significantly damaged. The purpose of this st...

The Japanese members of the chrysomelid subfamily Donaciinae are revised, 25 taxa including 22 species are recognized and four taxa are synonymized.
