Pesticides have been earning themselves a pretty bum rap these days.

USDA researchers have identified the neonicotinoid insecticide clothianidin as a likely contributor to monarch butterfly declines in North America.

It's no secret that the world's pollinators have been having a rough time of things these past few decades.

The critically endangered high brown fritillary had its best summer in a decade in 2014, with numbers rising 180% in a year thanks to conservation efforts

An environmental group sued the U.S. government on Friday, accusing regulators of discounting the dangers that a widely used herbicide poses to the declining monarch butterfly population.

They fly through the Louisville area each year on their way from Canada to Mexico — an iconic flutter of orange and black that has taught generations of Americans about the biology of life cycles a

Choice of variables, climate models and emissions scenarios all influence the results of species distribution models under future climatic conditions. However, an overview of applied studies suggests that the uncertainty associated with these factors is not always appropriately incorporated or even considered.

246 SPECIES, INCLUDING RARE BABY FIRE RING, SPOTTED

Leaves collected one year after the Fukushima nuclear disaster from surrounding regions had sufficient radioactive toxins on them to cause butterflies to die earlier and have deformed offspring.

The release of radioactive materials due to the Fukushima nuclear accident has raised concern regarding the biological impacts of ingesting radioactively contaminated diets on organisms. We previously performed an internal exposure experiment in which contaminated leaves collected from polluted areas were fed to larvae of the pale grass blue butterfly, Zizeeria maha, from Okinawa, which is one of the least polluted localities in Japan. Using the same experimental system, in the present study, we further examined the effects of low-level-contaminated diets on this butterfly.
