If someone had told me how much I'd enjoy science journalism, I would have been very surprised. Spending a day looking for a tiny beetle that's killing thousands of trees may not sound like your perfect office day, but I love the wonder and curiosity of it. . I like how dedicated scientists are to the little part of the world that they have decided to fix or make better. I like the ridiculous stories, like how the beetles from a sample ate through the bag and started chowing his nice wooden bookcase. I like how I can start the day knowing nothing about a subject and end up with lots of amazement and respect for it. And yes, I even like being that weird kid who can fill any awkward silence with 'did you know some fish communicate with farts?' Even that. . Thanks science, for letting me be your fan girl. #science #shotholeborer #urbanforest #trees #sciencejournalism #lovewhatyoudo #thanksscience #scienceinside

Why are there soda bottles hanging from trees? Well, they're beetle traps! Tiny beetles called Polyphagous Shot Hole Borers are a new pest found in Southern California. These beetles bore into trees to lay their eggs. They carry a fungus with them inside the tree to feed their larvae. The fungus grows and blocks waterways in the trees and causes fusarium dieback, ultimately killing the tree. Soda bottles are hung with a lure to catch the beetles to survey presence absence. The second picture shows a beetle found boring in tree. You can see just how small the beetle is! This is why it is important to not move your firewood, it's easy to transfer pests like these. For more information, contact your local agricultural commissioner's office. #UrbanEcology #polyphagousshotholeborer #ambrosiabeetles #Fusariumdieback #SantaClaraRiver #SantaClaraRiverWatershed #SantaClaraRiverWatershedConservancy #ExploreSCR #Entomology #SantaPaula #Fillmore #Oxnard #Ventura #VenturaCounty #PSHB #pestcontrol #ipm #buyitwhereyouburnit #dontmovefirewood
