When scientists discovered specimens of the invasive giant hornet Vespa mandarinia on both sides of the border between Washington and British Columbia in 2019, they sought to find out how they arrived from Asia. Analysis of their mitochondrial DNA provided an interesting twist: The hornets on each side of the border likely did not come from the same location in Asia.
In a look at the state of bee monitoring in the U.S., a group of researchers argue the commonly used bowl trap presents too many drawbacks to effectively study bee abundance and diversity.
The Rasopone genus of tropical leaf-litter ants gets a thorough taxonomic revision, and the researchers behind the long-term project present their identification manual in a "bird guide" format rather than the traditional dichotomous key.
A group of researchers gets creative with some simple materials: strips of cardboard, rolled up and tied with string. Affixed to tree trunks or limbs, the "trunk refugia" show promise as a simple and inexpensive tool for sampling tree-dwelling insects and arthropods.
It may be just one study of one species in one field in Virginia, but 20 years of monitoring Chinese mantid numbers there illustrates the potential double whammy of habitat loss (even a naturally occurring one) and climate change.
