European Oil Bee

One of only two Northern Hemisphere bees that collect floral oils instead of nectar as a food provision. It collects oils from yellow loosestrife flowers.

💡

Did You Know?

It mixes collected floral oil with pollen to create a waterproof, long-lasting larval food that resists mold in its damp underground nests.

Log Miner Midge

A wood-mining chironomid whose larvae bore into submerged decaying logs in streams. Larvae create visible galleries beneath the bark of waterlogged timber.

💡

Did You Know?

It is one of very few insects whose larvae can digest submerged waterlogged wood.
