A new study explores patterns of pigmentation and wing scale structure in Delias butterflies that reflect both visible and ultraviolet light. Researchers say the classical palette of warning coloration may contain colors that humans have long overlooked. https://t.co/Akh4MfiW1u

For entomology students, life does not always take place amid a crowded campus and busy hallways. One entomology graduate student shares how working and living at a remote research station has shaped her academic experience and career journey. https://t.co/pUKwSFhvn5

Sadly, today we echo the same sentiments ESA shared more than four years ago: https://t.co/crypgC4Bav.

Yesterday’s attack on Ukraine’s National Academy of Sciences is a tragic loss for science and a reminder of the senseless destruction of war. 🧵

On 28 September, a jet-powered drone slammed into the headquarters of the National Academy of Sciences of Ukraine in Kyiv, killing at least two people and destroying a section of the historic building. https://t.co/f8ZsSfjxwB

Science is not immune to the ills of global conflict, and protecting it is yet another reason to end this humanitarian catastrophe.

Since Carl Linnaeus published Systema Naturae in 1735, taxonomists have classified over 1 million species. A new special collection in Insect Systematics and Diversity celebrates the past, present, and future of insect systematics: https://t.co/0pNw7VzYdJ @OUP_Academic

Four out of five respondents to the survey say federal policies since 2025 have caused an "extremely negative impact" or "irreparable harm" on their field of science. https://t.co/nO0ZEq7dwr

[Entomological Society of America @EntsocAmerica]

For a second year, a survey of nearly 1,000 scientists across a variety of life sciences details how federal government policies have created ongoing disruptions to American research and to the scientific workforce. https://t.co/nO0ZEq7dwr

@UCRiverside Said Schroeder, “Taxonomy is the cornerstone of conservation. If we don’t describe species, we don’t know they exist & can’t conserve them. Honoring Taylor [by] naming these species after her is a way to honor conservation science & bring attention to all the unknown diversity.”

[Entomological Society of America @EntsocAmerica]

There’s one less blank space in taxonomy: ESA members and @UCRiverside researchers Sarah Schroeder and Christiane Weirauch have named a new insect genus after pop star Taylor Swift.

One telling data point from the study: Only 2.5% of at-risk insects and arachnids have nationwide protection under the U.S. Endangered Species Act, compared to 27.7% of at-risk birds. https://t.co/vxWmnjKHIv

[Entomological Society of America @EntsocAmerica]

Most U.S. insects and arachnids remain unassessed for conservation risk, and even many known at-risk species lack legal protection. A study quantifying this lag in arthropod conservation reveals a major blind spot in efforts to save vulnerable wildlife. https://t.co/vxWmnjKHIv
