Mosquitoes sense infrared from body heat to help track humans down, study shows

Infrared radiation from a source roughly the temperature of human skin doubled the insects' overall host-seeking behavior when combined with CO2 and human odor. […] It's only in the context of other cues, such as elevated CO2 and human odor that IR makes a [difference;] infrared alone has no impact.

Rauhoitettu kuoriainen löytyi Perämeren saarelta – lisää harvinaisuuksia odottaa löytäjäänsä

Luontopalvelujen meribiologit löysivät Perämeren Satakarilta harvakseltaan esiintyvän meriuposkuoriaislajin. Lajia on etsitty systemaattisesti vain mantereelta, saarten kartoitus todennäköisesti laajentaisi lajin levinneisyysaluetta.

Biologists discover caterpillars are able to sense electrostatic fields generated by predators

[The researchers tested specimens of cinnabar moth, the scarce vapourer moth and the European peacock butterfly] for the ability to sense and react to an artificially generated electrostatic field that matched the output of that generated by a wasp. [All] three species responded very clearly to an electrostatic charge—some flailed their bodies, others coiled in a defensive posture.

Brunneria borealis is the only praying mantis species that always reproduces asexually. Every individual across its U.S. range is female, and a new study finds little genetic variation among them, pointing to a relatively recent introduction. Researchers posit that a single female mantis that could reproduce without a male may be the origin for the entire population of the species in North America.

Are insects drawn to light? New research shows it’s confusion, not fatal attraction

Rather than being attracted to light, researchers believe that artificial lights at night may actually scramble flying insects' innate navigational systems, causing them to flutter in confusion around porch lamps, street lights and other artificial beacons.

Artificial Sweetener Could Be New Tool in Cockroach Management

German cockroaches fed sucralose in lab tests were less likely to survive after several days, with apparent links to water loss and changes in gut bacteria.
