This is a known behavior called the dorsal light response. In nature, assuming that more light comes down from the sky than up from the ground, this response helps keep insects in the proper orientation to fly. Artificial light at night interrupts the normal flight patterns of insect...

阅读理解The science of why insects gather around lights at night has never been nailed down. Popular theories propose that moths and other insects navigate(导航) by the moon and mistake lamps for moonlight, or that the insects fly towards light to escape coming danger. Now researchers believe ...
Night artificial light is a major cause of insect population loss, which could severely impact crop pollination and food supplies for larger animals, including humans. “Insects have been flying around for 370 million years, and it’s just in the last 150 years that it’s really gone wrong ...
Lights tend to lure(引诱) large numbers of outdoor insects at night.There’s even an old saying that describes this irresistible attraction:like a moth to a flame.But when it comes to attracting insects,not all lights are equal.Which ones are most alluring can be traced to the wavelengths...
However, a recent study (3) ___ the long-believed notion that insects head towards light because they like it. Biologists at Imperial College London have reported that insects are drawn (4) ___ light because it helps with their orientation when in flight. The scientists said artificial light...
t draw bugs to your house.The team conducted the test during the summer.They used only one type of bulb each night.At sundown,they put out the test equipment and turned on its light.At dawn the next day they collected any insects that had been drawn to the light and trapped.On nights...
the leading scientific hypothesis has been that insects use the moon's light to direct the way at night and mistake artificial lights for the moon. But this ide a doesn't explain why insects that only fly during the day also gather around lights.To find out what really happens, Samuel's...
“Line 21. I hope that information on how to identify these two species in the field (and whether there are other species active in these areas at the same time) is given in the methods section.” A2.14: This information is in the new subsection “Firefly natural history in Rancho del ...
But a new study suggests they may just lose track of which way is up.Previous theories say light probably blinds flying insects so that they get trapped by the light, or maybe they interpret light at night as a place to fly for a quick escape. Now the new study suggests flying insects...
