The Salad Bar
Are Pieris larvae picky eaters? Find out by providing them with
their very own salad bar.
Materials Needed
- Three plastic plates
- Six leaves for feeding trials*
- Three Pieris larvae from Brassica Barn
*Select
from members of the Brassica family (cabbage, Broccoli, turnips,
pak choi, kale, mustard greens, etc.) and non-Brassicas (lettuce,
beet leaves,
celery leaves,
carrot leaves, spinach, etc.).
Instructions
- Make three dime-sized portions from each leaf. You can also use a hole
punch to make more precise portions.
- Place one portion from each
leaf in a circular pattern near the outside of one plate. Repeat
this for the two remaining plates.
- Gently remove 3 Pieris larvae from
a Brassica Barn and place one in the center of each dish. You
can use more larvae if you
wish.
- Observe and describe what happens. Record results at 2 hours,
4 hours, and 24 hours.
Activity Questions:
- How did the larva(e) behave when introduced
into the container?
- Which plants did the larvae eat?
- Compare how much was eaten from each leaf.
- What can you conclude about the feeding preferences
of Pieris larvae?
