Interesting life cycle
Oil beetles have an amazing life cycle, intricately linked to that of solitary bees. After hatching, oil beetle larvae (known as triungulins) make their way onto a flower head where they lie in wait for a solitary bee. Using specialised hooks on their feet, they attach themselves to the back of a visiting female bee and when the bee returns to its underground nest, the triungulin disembarks and continues its development underground, eating through the bee’s stores of pollen and nectar. The following year, it emerges as an adult oil beetle ready to start the life cycle all over again.
