Higher temps may put monarch butterflies at risk
Higher temperatures may make monarch butterflies more vulnerable to parasites, according to new research. Monarch infections with the parasite Ophryocystis elektroscirrha have skyrocketed, more than...
View Article‘Supergene’ helps butterflies mimic wing patterns to stay safe
New research dissects how a single genetic switch helps butterflies mimic wing patterns of other species to protect themselves from predators. Many butterflies develop wing patterns that mimic other...
View ArticleInsecticide is the main driver of Midwest butterfly decline
Insecticide use is the single largest factor contributing to a decline in total butterfly abundance and species diversity in the Midwest United States, according to a new study. “What drives butterfly...
View ArticleRare butterflies in Denmark are in steep decline
The distribution of rare butterflies in Eastern Denmark has plummeted by 72% in just 26 years, according to a new study. The findings indicate that current conservation efforts do not seem to be...
View ArticleGene jump explains why some butterflies see color differently
In at least one species of butterfly, the variation in the vision of males and females results from a vision gene’s jump onto a sex chromosome. As butterflies flit among flowers, they don’t all view...
View ArticleThese aphids make milkweed less appealing to monarchs
When oleander aphids infested tropical milkweed, monarch butterflies laid fewer eggs on the plants, and developing caterpillars were slower to mature, according to a new study. Tropical milkweed is a...
View ArticleMonarchs with more white spots are better at long trips
Monarch butterflies with more white spots are more successful at reaching their long-distance wintering destination, a new study suggests. Although it’s not yet clear how the spots aid the species’...

Unseasonably warm and cold days can prolong the active period of moths and butterflies by nearly a month, according to a new study. As Earth’s climate continues to warm due to the emission of...
View ArticleFirst butterflies winged off from North and Central America
Scientists have discovered where the first butterflies originated and which plants they relied on for food. About 100 million years ago, a group of trendsetting moths started flying during the day...
View ArticleCity butterflies find refuge in botanical gardens
Despite their relatively small footprint in urban areas, botanical gardens are important hotspots for butterfly biodiversity in the arid Southwest, according to a new study. Using more than 10,500...
View ArticleRuthless parasite plagues monarch butterflies
Monarch butterflies, one of the most iconic insects of North America, are increasingly plagued by a debilitating parasite, a new analysis shows. Researchers drew from 50 years of data on the infection...
View ArticleButterfly eyespots reuse genetic code for legs, wings, and antennae
New research reveals that complex traits in butterflies, such as eyespots, evolve from gene networks already operating in the body to build antennae, legs, and even wings. Butterflies use eyespots, the...
View ArticleButterflies inspire artificial colors for 3D printing
Researchers have created artificial colors by 3D printing certain nanostructures inspired by those of a butterfly. This principle can be used in the future to produce color screens. For their new...
View ArticleCabbage butterflies evolved tastes to keep up with plant defenses
Cabbage butterflies started trying to take over the planet millions of years before humans ever set foot on it, researchers report. Their new study uses statistical methods to trace the path of ancient...
View Article1 western butterfly population has dropped 99.9% since the 1980s
Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report. The report, published in Science, looks at more than 450 butterfly species, including the...
View ArticleBirds may avoid fast, flashy butterflies and their mimics
Birds can learn to recognize fast and flashy butterflies they’ve failed to catch in the past—as well as similar-looking species—research finds. The research provides some of the strongest evidence to...
View ArticleTexas cold snap could be really bad for monarchs
The recent frigid weather in Texas and Mexico will likely hit the monarch butterfly population especially hard, a new study shows. Figures show a dramatic 50% decline in their numbers over the last...
View ArticleMonarchs lay more eggs where milkweed isn’t alone
A new study suggests mixing milkweed with other flowering plants may help migrating monarch butterflies more than milkweed alone. As monarch butterflies make their transcontinental migration this month...
View ArticleHow gross ‘chastity belts’ shape butterfly evolution
New research digs into the role sexual conflict between male and female plays in butterfly evolution. Some male butterflies go to extreme lengths to ensure their paternity—sealing their mate’s...
View ArticleBlame milkweed loss for steep monarch declines
A loss of milkweed, and not increased death during migration, is the most likely cause for a steep decline in the monarch butterfly population in the last few decades, evidence in a new study suggests....
