Bark beetles! As a member of the beetle subgroup Scolytinae, they’re more like weevils. When they’re feeding and reproducing in the phloem of spruce trees, they’re dragging around a fungus with them that is not good for the tree. Scientists are hard at work trying to figure out how to keep the weevil and the fungus from killing trees. What’s interesting, though, is that some trees are resistant to the wiles of this biological onslaught. It would be great to know the specifics of that defense mechanism.
Bark beetles (Ips typographus) come in many colors from rust orange to blue-black, just like on this mug.
Choose from either
• standard mug 325 ml (11 oz)
• tall mug 440 ml (15 oz)
• latte mug 500 ml (17 oz)
All are glossy white with a vivid bark beetle print that retains its luster through the microwave and the dishwasher.
Enamel Mug The white enamel mug with a silver rim holds 350 ml (12 oz). It's robust enough to take with you on field research or camping. Please wash by hand; it is not dishwasher or microwave-safe.
