Background. Cryptotympana atrata and Hyalessa fuscata are the most abundant cicada species in the Korean Peninsula, where their population densities are higher in urban areas than in rural ones. The urban heat island (UHI) effect, wherein human activities cause urban areas to be significantly warmer than surrounding rural areas, may underlie this difference. We predicted a positive relationship...

The cicada genus Haphsa Distant from China was reviewed based on the description of a new species (Haphsa lueta sp. n.) and redescriptions of other three known species which are reported from China for the first time. A key to all known species of Haphsa worldwide is provided. The geographical distribution of the Haphsa species and the availability of Haphsa dianensis Chou, Lei, Li, Lu & Yao, 1...

The distributions of American cicada killers (Sphecius) were examined via solicited and museum specimens. S. hogardii occurs in southern Florida and several Caribbean islands. S. speciosus occurs throughout the east coast, southeast, and Midwestern states at high densities, and its range extends much farther west than expected, but not west of the continental divide. S. speciosus appears to be ...

Cicadas are known to use sound to find a mate. While the mechanism employed by male cicadas to generate loud calling songs has been described in detail, little information exists to explain how their ears work. Using microscanning laser Doppler vibrometry, the tympanal vibrations in the cicada Cicadatra atra are measured in response to acoustic playbacks. The topographically accurate optical me...

Annually emerging cicadas are a numerically and ecologically dominant species in Southwestern riparian forests. Humans have altered disturbance regimes that structure these forests such that floods are less common and wildfires occur more frequently than was historically the case. Impacts of these changes on primary consumers such as riparian cicadas are unknown. Because cicadas are consumed by...

Cicada wings consist of nanopillar arrays with a pitch, diameter, and height few hundred nanometers. These show strong antibacterial performance owing to cell membrane damage caused by the physical interaction nanopillars. Polymer-based nanopillars are essential for various industrial applications. Herein, we present fabrication process polymer-based using facile thermal nanoimprint technique. ...
