How High Can You See Monarchs
as They Fly Overhead?

Here's how we used the pictures:
We looked for something familiar in each picture (e.g., a road, a house, a car, a person). We thought about the size of a monarch butterfly in comparison. Then, for each altitude, we decided if we could possibly see a monarch at the same distance.

  • Try it yourself! >>
  • Then see our conclusion >>
This car is about 508 cm (200 inches) long. Monarchs are about 10 cm (4 inches) wide, including their wings.
