In our classroom, my firsties and I had a great time witnessing the metamorphosis of our Brassica caterpillars. I am delighted with the way this unit turned out. I used to order the Painted Lady larva, but it was hard for my kiddos to truly understand that caterpillars eat leaves because they came with that brown sludge in the cup instead, plus we never saw the egg part of the life cycle at all. This year I decided to cross my fingers and buy butterfly eggs from Carolina Biological instead. It was actually the same price ($14.99) to buy the eggs as it would be to buy caterpillar larva from another site. In addition, we had over 9 caterpillars hatch, and as of Friday afternoon, we had 9 butterflies compared to the 5 or 6 caterpillars I'd gotten in the past from other sites. I'm definitely doing this again next year!
