A new species of Onychotrechus Kirkaldy, 1903 (Hemiptera, Heteroptera, Gerridae) from Dooars, West Bengal, India, and a key to males of all species

open access: yesDeutsche Entomologische Zeitschrift, 2014
A new species of hygropetric water strider, Onychotrechus dooarsicus sp. n. is described from Buxa Tiger Reserve, Dooars, West Bengal, India. Representatives of the new species were collected from a stream with boulders and rocks splashed by water, with ...

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

open access: yesAdvanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Dispersal and reproductive responses of the water strider, Aquarius paludum (Hemiptera: Gerridae), to changing NaCl concentrations

open access: yesEuropean Journal of Entomology, 2007
The responses of females of the water strider, Aquarius paludum, to changes in NaCl concentration were examined in the laboratory. The insects were sampled seasonally in 2002 and 2003 at two reservoirs in Kochi, Japan, connected by a waterway, one at the

Bioinspired Aquatic Microrobot Capable of Walking on Water Surface Like a Water Strider

open access: yes, 2016
Walking on the water surface is a dream of humans, but it is exactly the way of life for some aquatic insects. In this study, a bionic aquatic microrobot capable of walking on the water surface like a water strider was reported.

Influence of male density on guarding behaviour in the water strider Aquarius paludum (Heteroptera: Gerridae)

open access: yesEuropean Journal of Entomology, 2011
In species with last sperm precedence, post-mating guarding behaviour by males is effective for avoiding sperm displacement by additional males. However, for males to guard their mates under all circumstances may be undesirable, particularly when the ...
