the nature diaries

Spotted wings and city trees,
A quiet hitchhike overseas.
We built the ships, we paved the way,
Then cursed the guests who chose to stay.
Crush the bug, that’s what we do,
But who’s to blame, me or you?

Where I live, everyone knows what to do when they see a spotted lanternfly. You’re supposed to kill it on sight. No hesitation. No sympathy. It’s almost a reflex now. Step. Smash. Move on. There are signs about them at parks and posts about them online. They’re invasive, we’re told. They damage trees, vineyards, and crops. They don’t belong here.

The spotted lanternfly was first detected in the United States in 2014, and since then, it has spread rapidly across parts of the East Coast. It feeds on sap from hardwood trees and agricultural plants, especially grapes and certain ornamental trees. In places like Pennsylvania and New Jersey, vineyards have suffered measurable losses. Residents are encouraged to scrape egg masses off tree bark and crush adults on sight.

I understand the reasoning. When a species arrives without its natural predators and begins to overwhelm local ecosystems, the consequences ripple outward. Native plants weaken, and dependent insects lose food sources. Farmers lose crops. Economies feel it. Ecologists use the word “invasive” to describe species that spread aggressively and cause harm, and in that scientific sense, the lanternfly fits.

But sometimes I pause, just for a second, before I step.

Because the lanternfly didn’t choose to be here. It likely arrived through international shipping, hidden in cargo or packing materials. It didn’t cross oceans on its own, and it’s thriving in the kind of landscape humans have created: fragmented forests, ornamental tree plantings, highway corridors, suburban developments. Disturbed environments often favor adaptable species. The lanternfly happens to be one of them.

We call it invasive because it spreads fast and crowds out what was here before. Native species evolved together over thousands of years, forming relationships that are delicate and deeply interconnected. When something new enters that web, it can unravel more than we see at first glance.

Still, I can’t ignore how often the language feels loaded. “Invasion.” “Takeover.” “Destroy.” It makes nature sound like a battlefield, and the lanternfly like a villain in a story it didn’t write.

The more uncomfortable truth might be that invasions often follow disturbance. We clear forests. We pave land. We transport goods across continents. We warm the climate. And certain species, those that are adaptable, opportunistic, resilient, succeed in the gaps we create.

Managing invasive species is necessary. Native ecosystems deserve protection. But stopping at the lanternfly misses the bigger picture. We are the most widespread and transformative species on the planet. We move organisms across oceans, alter climates, and redesign entire habitats — then act surprised when some species adapt faster than others. If we’re serious about ecological balance, our solutions have to address more than just what we can step on.
