Morrison bumble bee proposed for protection, news for World Bee Day

Happy World Bee Day! As I have since 2022, I'm concentrating on bumblebees.* Today, I'm amplifying the relevant part of Xerces Society for Invertebrate Conservation's press release, Morrison Bumble Bee and Large Marble Butterfly to be Considered for Endangered Species Protection.*

Responding to petitions filed by the Xerces Society, last week the U.S. Fish and Wildlife Service (FWS) announced that the Morrison bumble bee (Bombus morrisoni) and the large marble butterfly (Euchloe ausonides) warrant further consideration for protection under the Endangered Species Act, by issuing a positive 90-day finding for these two species.

Next, Fish and Wildlife will carry out a full review (called a Species Status Assessment) of the two species. Once these are completed, FWS will decide whether or not listing these species as threatened or endangered under the Endangered Species Act is warranted. If listing is warranted, legal protections will go into effect and resources will be directed to recovery.

Morrison bumble bees have disappeared in many places
The Morrison bumble bee historically occurred across much of the western U.S., and can be found in grasslands, sagebrush steppe, and woodland edges. It has co-evolved with local plants for thousands of years and is a super-pollinator, contributing to the stability of our wildlands and agricultural systems. However, the species has disappeared from much of its range and may have declined by as much as 75%. It faces multiple ongoing threats, including habitat loss and degradation, overgrazing, climate change, pesticides, diseases, and competition with honey bees. The Xerces Society petitioned FWS to protect this bee in 2023.

These pollinators need federal protection to survive
ESA listings would protect these species by addressing the threats they are facing and ensuring that regulatory mechanisms — which are currently lacking — are in place to protect the species in locations where they are needed most. Federal protection is especially important for the Morrison bumble bee and the large marble butterfly because they occur in several states where state wildlife agencies lack the legal authority to protect insects and are unable to address the conservation needs of these species.

We lose something precious when a species goes extinct. Morrison bumble bees and large marble butterflies are integral parts of the unique landscapes that make the western U.S. so special. Our world would be a duller place without the pleasure of watching this vibrant butterfly and bright yellow bee tumble from flower to flower.

May both the Morrison bumble bee and large marble butterfly earn protection under the Endangered Species Act, and may the Endangered Species Act still include habitat protection, which the Trump Administration wants to remove. This is even more than they tried last time, which resulted in fewer species being listed. I'm crossing my fingers.

Even if these proposals go into effect, all may not be lost. The Nevada Independent published Bees, butterflies and beetles — bill would allow Nevada to manage certain invertebrates: "If passed, the state's department of wildlife would gain permission to protect 66 of Nevada’s most imperiled insects." The article specifically mentions the Morrison bumble bee. May it pass, too.

That's a wrap for today's biodiversity holiday, although I plan on returning to the general topic on Thursday, which is International Day for Biological Diversity. In the meantime, stay tuned for Wayback Wednesday.

*Honeybees have their own day. I'll remember them in three months.
