This week we have science activities and resources for learning more about butterflies and moths, Order Lepidoptera.
What are butterflies and moths?
Members of the Order Lepidoptera have four scale-covered wings as adults. They go through complete metamorphosis and the larval stage is commonly called a caterpillar. One unique trait of the Lepidoptera is that an adult butterfly’s or moth’s mouthparts, called a proboscis, is curled up under the head when not in use. The proboscis straightens out like a party favor blower when the butterfly or moth feeds.
The larval stages of butterflies and moths feed on plants (with a few rare exceptions). The adults feed on various liquids or don’t feed at all. Many visit flowers for nectar.
Activity:Â Demonstrate how the butterfly moth works with a party blower.
2. What are the differences between butterflies and moths?
See our Growing with Science website for a longer discussion of the differences between butterflies and moths.
Activity:Â Gather illustrations of common butterflies and moths and have the children sort them into groups using what they have learned.
3. Butterfly and moth life cycles
Check our Growing with Science website for a detailed discussion of butterfly and moth life cycles.
Activity:Â Draw the life cycle of a butterfly and label all four life stages.
Butterflies have four life stages: egg, caterpillar (larva), chrysalis (pupa), adult.
Ask-A-Biologist has a monarch butterfly life cycle coloring page .pdf to download or print.
Activity: Draw the life cycle of a moth and label all four life stages.
Moths also have four life stages, but instead of a chrysalis the pupa is either bare, or develops within a wrapping of silk called a cocoon.
Ask-a-Biologist has a Manduca moth life cycle coloring page .pdf to download or print. Note:Â Manduca moths do not form a cocoon.
To see a moth that does form a cocoon, try our Silkworm Moth Life Cycle post.
4. Butterfly and Moth Anatomy
The Growing with Science website also has a discussion of adult butterfly and caterpillar anatomy.
Activity:Â Caterpillar anatomy
Allow the children to observe a live caterpillar if available, or obtain some realistic plastic toy caterpillars if not. Explain that insect have six legs and caterpillars are not an exception, although it may look like they have more. The caterpillar has six true legs on its thorax (section right behind the head), but has additional fleshy appendages on the abdomen called prolegs. Those are not truly legs and are mostly used for gripping the plant.
5. Go on a caterpillar hunt outdoors
Young children benefit from experience being outdoors and seeing caterpillars in their natural habitat. If you are unsure where to look, find an experienced guide and/or scout the area in advance.
