#Fungi disarm #BarkBeetle chemical shields by converting their plant-derived toxins phys.org/news/2025-12-fungus-b… pnas.org/doi/10.1073/pnas.2525…
"a bark beetle can co-opt a tree's defensive compounds to make defenses against its own enemies. However, since one of the enemies, the #fungus Beauveria bassiana, has developed the ability to detoxify these antimicrobial defenses, it can successfully infect the #BarkBeetles and thus actually help the tree in its battle against bark #beetles"
Fungus disarms bark beetle chemical shields by converting their plant-derived toxins
Spruce bark is rich in phenolic compounds that protect trees from pathogenic fungi. A research team at the Max Planck Institute for Chemical Ecology in Jena has investigated how these plant defenses function within the food web, particularly in spruc…Max Planck Society (Phys.org)
Dung Beetles Are Rainforests’ Diligent Regrowth Soldiers
The dung beetle may eat and nest in poop, but their role in nature is anything but humble. These hardshelled scarabs live on every continent except Antarctica, recycling feces and suppressing paras…Palm Oil Detectives

Pollinator Week is a great time to share this print, which expresses the central theme of my work about the Future of Pollination for Manufactured Ecosystems. Our food sources & ecosystems around us are dependent on pollinators (mostly bees & other insects, some birds & mammals) but insects populations have lost huge numbers and many species altogether.🧵

I would never have seen this fellow if he hadn't moved. He's tiny and the color of the sand in this creekside sandbar.

Poteriophorus imperatrix observed by Claude Chavand
Poteriophorus imperatrix from San Jose, Padilla, Antipolo, Rizal, Philippines on April 13, 2019 at 10:05 AM by Claude Chavand. This big weevil (around 30mm long without rostrum) was found walking on stones on a river bank cl...iNaturalist
Entomology never fails to surprise. We found this metallic Phanolinus rove beetle in an Ecuadorian cloud forest.

#Bostrichidae #beetles have two #symbionts with important functions. One encodes the pathways to produce tyrosine precursors and is presumably involved in #cuticle and #exoskeleton formation. The second recycles urea, synthesizes lysine, and is strictly #evolving with its host. These types of "dual symbioses" have only been described in sap-feeding #Hemiptera.

Cuticle supplementation and nitrogen recycling by a dual bacterial symbiosis in a family of xylophagous beetles (Coleoptera: Bostrichidae)
Many insects engage in stable nutritional symbioses with bacteria that supplement limiting essential nutrients to their host.bioRxiv
