I recently ran across this gorgeous beetle while hanging out with writer Scott Huler on his ambitious Lawson Trek. I didn’t know what species it was, but figured it would be pretty easy to ID when I got home (it was). As I began researching this insect, I quickly realized that the Patent-Leather Beetle (Odontotaenius disjunctus) should be nominated for a Best Insect Award.
1. Great Personality
This very large beetle with scary looking mouthparts won’t hurt you. It rarely flies and it’s a pretty slow walker… so no sudden movements and no buzzing around your head. I like that in an insect. And those horrifying chompers? They’re used to chew through logs, not people. Thank you, evolution.
2. Cool Appearance
Ooo, shiny! Plus, it’s a terrific insect for anatomy practice. First, no microscope needed. Second, that clear-cut case of head, thorax, abdomen? Not so fast. The abdomen-looking structure is actually a grooved set of hardened wings called elytra. And that thorax-looking structure? Well, it is PART of the thorax. The other section is underneath those elytra. Way to keep things interesting!
3. No Sexism
Both males and females contribute to rearing their young and keeping the home safe and tidy. This social structure is not common among beetles (see another post about equality-minded beetles).
4. Ecological Service
Patent-leather beetles don’t just raise their family in logs. They also eat and decompose the wood, recycling nutrients back to the forest floor.
5. Kiss Language
These beetles communicate with each other through a number of different calls. Many calls sound like the noise you make when blowing someone a kiss. Larval patent-leather beetles even have a modified third set of legs that create noises to communicate with parents (“Ma, I’m hungry!” “Watch me, Dad!”)
Want to learn more about the awesome Patent-leather beetles (and hear their kiss-calls)? Here’s a great resource from the University of Florida.
The most amazing aspect of the human species (Homo sapiens) is our power to change our environment. Using this capacity, we’ve created societies in almost every corner of the Earth. We construct islands, create inlets and waterways, and move dunes to secure a coastal view. We cut tremendous forests and construct remarkable dams. And we eliminate entire mountains in our search for ores and coal. We even change the temperature and weather patterns of our planet.
This may sound bleak, but I don’t see it that way. With so much influence and ingenuity, we can protect our planet. We have the power to reduce and repair environmental impacts. It all begins with awareness, resolve, creativity… and responsibility.
Mind the wisdom of Spiderman’s Uncle Ben: “with great power comes great responsibility.”
See that tiny bump on the branch? You’re looking at a mom protecting hundreds of babies. Well, actually, the mama Oak Scale insect (Parthenolecanium quercifex) is dead now, but her exoskeleton is still harboring those little eggs underneath. When those baby Scales hatch around the end of May, the tiny darlings will move out to the oak leaves and begin to SUCK THAT POOR TREE DRY. They sniff out the precious sugar-water flowing through veins in leaves, insert their straw-like mouth parts and drink up. As the year progresses, Scales grow and mate. Mama lays her eggs beneath her and dies, making way for next May’s new generation.
(These are the eggs… um, on my kitchen table. Didn’t realize they’d pop out like that when I lifted the mama Scale off. Oops.)
In the insect’s defense, healthy trees can resist Scale infestations. Some leaves and twigs may fall off – that’s all. But trees that are weakened (by physical damage, drought, chemicals, etc.) can be killed by the insects.
Cool Climate Change research recently found that densities of Oak Scale are up to 13x higher in warm urban areas! (1) Since things are getting toastier here on Earth, we may want to get more familiar with the life & times of the Oak Scale.
