Ants 🐜 moved on up and out! New paper w @CorrieMoreau, Kevin Boyce, @rree73, where we asked how/when did #ants shift from ground to arboreal nesting🌳 & from forests to open habitats 🏜️. We suggest both are linked to #angiosperm evolution. 👇 @FieldMuseum

Today, winter is reasserting itself in #PrinceGeorgesCounty, but springtime #angiosperm sex had already been moving into high gear in our yard over the past month.
