It’s taken nearly 200 years, but scientists in Arizona and Europe have teased out how the molecular switch for sex gradually and adaptively evolved in the honey bee. The first genetic mechanism for sex determination was proposed in the mid-1800s by a Silesian monk named Johann Dzierson, according to the study’s co-author and Arizona State […]

As the largest dam removal in U.S. history brought Pacific salmon back to Washington state’s Elwha River for the first time in nearly a century, scientists were considering the changing ecosystem’s impact on those foundational Elwha Valley dwellers: insects. In the spring, entomology professor Richard Zack brought to Washington State University some millions of specimens […]

It looks like spiders may not be the pure predators we generally believe them to be. Dr Dirk Sanders of the University of Exeter has demonstrated that orb web spiders choose to eat pollen, even when insects are available. His research appears in a PLOS One article called “Herbivory in Spiders: The Importance of Pollen […]

The findings of a study by a team of academics led by Swansea University could have far-reaching implications for the control of mosquito larvae across the world. The study, recently published by the PLOS One research journal, shows the mechanisms by which a fungus called Metarhizium anisopliae kills mosquito larvae, which could help efforts to […]

Now you can Help Digitize Insect Collections from your own Home

CALBUG-FEATURE

What do you do with a million insect specimens and labels that need to be entered into a database? The Essig Museum of Entomology in California faced that problem and calculated that it would take their current staff about 100 years to digitize the eight major insect collections in the state. Instead, they decided to […]
