☆ New study finds invasive Jorō spiders ‘keep cool under pressure’

… It seems like even though their heart rate does accelerate, it’s much more even (than the other spider’s heart rates),” he added. To test the spiders’ heart rates, Davis and study coauthor Christina Vu, who was a University of Georgia undergraduate student of entomology at the time, wrangled 79 spiders from two different genera. The Jorō spiders (top left) had to be carefully restrained using pins in order to measure the arachnids' heart rates. They compared the spiders’ resting heart rates to their heart rates during restraint and found all the spiders’ heart rates increased, but the Argiope spiders, which are known to avoid urban settings, had many more spikes as they struggled to run away, according to the research. … To observe spider heart rates, they must be restrained in the first place, which causes a heart rate elevation,” he said.

☆ How a group of butterflies flew 2,600 miles across the Atlantic Ocean without stopping
  + stars: | 2024-07-01 | by ( Taylor Nicioli | ) edition.cnn.com   time to read: +7 min
Scientists have now found evidence that a group of the winged travelers flew over 2,600 miles (about 4,200 kilometers) across the Atlantic Ocean without stopping, according to a new study published June 25 in the journal Nature Communications. The insects, which are not usually found in South America, were worn out with holes and tears in their wings. Tracking a butterflyResearchers took a few crucial steps to confirm these out-of-place butterflies really did travel across the ocean. By this method, the scientists concluded the butterflies’ birthplace to be in either Western Europe, North Africa or West Africa, she added. The researchers hope to use the same techniques to investigate the migration patterns of other species of butterflies, she added.

☆ Invasive Jorō spiders can live well with humans, according to new study

Typical spiders — and most creatures — tend to find the noise and wind disturbance from nearby busy roads to be too stressful, but the Jorō spider doesn’t seem to mind much, according to a new study published in Arthropoda on February 13. University of Georgia ecology students and study coauthors Kade Stewart, Caitlin Phelan and Alexa Schultz handle a Jorō spider. What to do when you come across a Jorō spiderAs the nonnative Jorō spider continues to spread in the region, the spiders pose a threat to native species that are beneficial to the environment. While conducting the study, the researchers found evidence of the Jorō spiders coexisting with native spiders, Davis said. And the Jorō spiders eat species that are good and bad for the environment, including the infamous lantern fly, he added.

☆ ‘Moths to a flame’: Insect behavior around light isn’t about attraction, scientists say
  + stars: | 2024-02-07 | by ( Taylor Nicioli | ) edition.cnn.com   time to read: +7 min
Gaining a better understanding of the impact of artificial light on these winged creatures is crucial as light pollution plays an increasing role in the decline of global insect populations, the researchers wrote. Artificial light confuses nocturnal insectsWhen artificial light does not interfere, nocturnal insects keep their backs pointed toward whatever direction is brightest, which is typically the sky versus the ground. By using insect-scale motion-capture cameras, the researchers determined that the flying insects exhibited three consistent behaviors: orbiting, stalling and inverting. Moths and other insects can become trapped in a disorienting orbit around artificial light sources such as street lamps and porch lights. The new findings could help with conservation by fueling research on how to minimize the effects of light pollution on the insects, Dombroskie said.

☆ Fact Check-Video shows an aphid, not a genetically modified mosquito ‘released by Bill Gates’

A video circulating online shows a small sap-sucking insect called an aphid, not a genetically modified mosquito with a number stamped on it released by philanthropist Bill Gates, as online posts claim. Bill Gates was very vocal about releasing millions of GMO [genetically modified organism] mosquitos into the public.”Another example can be seen (here). However, the video shows a small insect called an aphid, not a GMO mosquito. A representative for the Gates Foundation said the claim that the video showed a genetically modified mosquito with a number or barcode stamped on it released by the Gates Foundation was false. The video shows an aphid, not a mosquito with a number stamped on it and released by Bill Gates.
