Wood-carving Leafcutter Bee

A large, dark leafcutter bee that nests in rotten wood and dead tree stumps across Europe. Females cut large leaf pieces from roses, birch, and willows.

💡

Did You Know?

Unlike most leafcutter bees that use pre-existing holes, it chews its own nest cavities directly into soft rotten wood.

Rice Stem Borer

A small white moth whose larvae bore into rice stems, causing the devastating symptoms known as 'dead heart' in vegetative stage and 'white ear' in reproductive stage. It is one of the most serious pests of rice in Asia.

💡

Did You Know?

A single larva can destroy an entire rice tiller by boring into the stem and feeding on internal tissue from the inside out.
