Zoology Science Fair Project

The Painted Lady Butterfly

The Painted Lady Butterfly | Science Fair Projects | STEM Projects
See the amazing metamorphosis of the Painted Lady butterfly as it changes from a caterpillar to a beautiful butterfly in just a few days. Put caterpillars in different temperatures and watch the transformation happen faster or slower.


The hypothesis is that the metamorphosis of the Painted Lady butterfly will occur more quickly at higher temperatures.

Method & Materials

You will place caterpillars in three different tanks with different temperatures and observe how long it takes for them to transform into butterflies.
You will need three transparent fish tanks, sixty Painted Lady butterfly caterpillars, three leafy plants, an air conditioned room, an incandescent lamp, and three thermometers.


The results showed that the Painted Lady butterflies that were placed under the incandescent lamp at 30° C were the fastest to complete the transformation, followed by the butterflies in the tank under normal room conditions.

Why do this project?

This science project is interesting and unique because it allows us to observe the transformation of caterpillars into butterflies in just a few days.

Also Consider

Experiment variations to consider include placing the butterfly chrysalis inside a copper coil with magnetic fields, or repeating the experiment with mealworms to observe the metamorphosis of beetles.
