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.

Imperial Moth

A large moth with bright yellow wings variably marked with purple-brown spots and patches. It is one of the most recognizable saturniids in the Americas.

💡

Did You Know?

The imperial moth has declined dramatically in the northeastern United States, likely due to parasitic flies introduced for gypsy moth control.
