Since butterflies start out as caterpillars we learned about the caterpillars anatomy for our second day of our butterfly unit study. We had fun with some math, literature, crafts, spelling, and of course science. We also made a caterpillar lunch today.
1. Discuss: Butterflies do all of their growing during the larva stage (caterpillar). Like all insects they have three distinct body parts (head, thorax, and abdomen). The head has a pair of short antennae, mouth parts (upper lip, mandibles, and lower lip), and six pairs of simple eyes, called ocelli, that can detect light and dark. Even with all of these eyes, the caterpillar’s vision is poor. Each body section has a pair of jointed, called true legs, while some of the abdominal segments have false legs, called prolegs. The body has tiny holes that the caterpillar uses to breath called spiracles. The caterpillar also has tiny hairs along his body that sense touch called setae.

Edible Caterpillar Cocoons
- 1- 8 oz. tube refrigerated crescent rolls
- 4 hotdogs
- 1 ketchup
- Preheat oven according to directions on the crescent-roll package. Separate the crescent-roll dough into its pre-cut triangle pieces, and lay them flat.
- Cut the hot dogs in half and place one half hotdog on each crescent-roll. Roll and bake on a cookie sheet according to package instructions. Dip in ketchup and enjoy.
- What a fun lunch for the kids, and for dessert I had made caterpillar cupcakes for them.
Label the Caterpillar Parts
We did the Label the Caterpillar Parts diagram to review what we had learned today. I used the diagram in the front of Creepy, Crawly Caterpillars by Margery Facklam and the Caterpillar Anatomy page to help with the review.
Green, purple, yellow, white paint
- Cut the bottoms off of a couple of empty egg cartons.
- Paint them green, purple, and yellow.
- After they dry, turn the green ones into heads, with goggle eyes and pipe cleaner antennae.
- Paint letter on top of the yellows (two sets of vowels), and purples (only one set of consonants.)
- After those dry, you can practice your alphabet, and simple spelling skills.
- We used them to review our spelling words for the week.
