Thorn-Thistle Borer

Eryngiorestis thorntoni

Generation 3 · descended from Trichodes ornatus (False Blister Beetle)

Trichodes ornatus, which previously fed on a variety of plants, began to specialize on Eryngium (Thistle) and similar spiny plants. Over generations, its larvae developed the ability to bore into the tough stems of these plants. As a defense, the adults evolved camouflage on their elytra to blend in with the thistle spines, reducing predation risk. This specialization allowed them to thrive in areas where other beetles struggled to survive.
