“Green Ladybugs” honeybees and butterflies feast on thistle nectar high in the Great Smoky Mountains. These pretty green ladybugs, are not really ladybugs at all, but Spotted Cucumber Beetles! They are native and non-invasive and normally live quiet lives in the forests and meadows doing little damage, but when they invade backyard gardens and farms they become a serious agricultural pest. There really are no greenish ladybugs – ladybugs are more “rounded” and have very short antennae compared to the cucumber beetles.
New research shows how an insect common to the Eastern U.S., the long-horned passalid beetle, has a hardy digestive tract with microbes to thank for turning its woody diet into energy, food for its young, and nutrients for forest growth. These insights into how the beetle and its distinct microbiome have co-evolved provide a roadmap for the production of affordable, nature-derived fuels and bioproducts: here.
