Costa Rica is a great place to be a wasp.
The weather’s always above freezing, and the wasping is easy…
On an upstairs porch ceiling there was a growing nest of small wasps.
A few feet away, a large polistes wasp was just getting started with her nest. Her first two offspring have capped their cells and are pupating. Two other cells have larvae, and in the smallest, newest cell an egg is visible.
On a walk nearby I noticed a water tap not too far from the composting shed.
From the faucet came a slow but steady drip. The brick’s corner was washed to bright red, and farther out the surface was covered with green algae.
Guanacaste is dry much of the year. A steady water source like this was enough to attract this thirsty wasp. And a fly.
How does a thirsty wasp find water?
I don’t know.
