How Sweet It Is
Adult Pieris feed upon the nectar of Brassica plants. Nectar is sweet,
but is it possible that varying levels of sweetness might have an
impact on Pieris feeding?
Materials Needed
Instructions
- Place the film
can sugar feeders, prepared as
described, into
a Light House containing adult Pieris butterflies.
- Observe the feeding
behavior of the butterflies.
- For each feeder, keep track of how
many butterflies feed during a specific time period.
- Keep
track of how long the butterflies spend feeding at each Feeder.
- Leave
the Feeders in the Light House for a 48-hour period. At the
end of this period, compare how much sugar solution
is left in
each.
Activity Questions:
- How did the butterflies behave when introduced
to the Feeders?
- How would you describe the way that the
butterflies “tasted” each
solution.
- Which solutions, if any, were preferred
by Pieris? What’s
your evidence?
