Odorous House Ant

A small dark brown ant that emits a distinctive rotten coconut smell when crushed. It is one of the most common household pest ants in North America.

💡

Did You Know?

The smell produced when crushed is caused by methyl ketones, the same compounds found in blue cheese.

Broad-footed Colletes

A rare coastal specialist plasterer bee that forages on sea aster in saltmarsh habitats. It is restricted to a narrow band of habitat along European coasts.

💡

Did You Know?

Rising sea levels and saltmarsh erosion directly threaten its nesting sites, making it one of the bees most vulnerable to climate change.
