15 Vocabulary Words Included
Here are the 15 words hidden inside this puzzle, along with their thematic definitions for classroom discussions:

CHRYSALIS
The hard-shelled pupa stage of a butterfly, inside which transformation takes place.
LARVA
The active, immature form of an insect, especially one that differs greatly from the adult (e.g., a caterpillar).
PUPA
An insect in its inactive, non-feeding developmental stage between larva and adult.
TADPOLE
The tailed aquatic larva of an amphibian (frog or toad), breathing through gills before growing legs.
COCOON
A silky protective case spun by moth caterpillars for protection during the pupal stage.
HATCHLING
A young animal that has recently emerged from its egg.
ADULT
The fully grown, mature stage of an organism capable of reproduction.
BUTTERFLY
A diurnal insect of the order Lepidoptera with large, often brightly colored wings.
AMPHIBIAN
A cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, and salamanders.
CYCLE
A recurring series of biological events that regularly repeats in the same order.
STAGES
The distinct, observable phases in the life history of an organism.
REPRODUCTION
The biological process by which new individual organisms (offspring) are produced.
MOLTING
The shedding of an old outer cuticle or exoskeleton in arthropods to allow for body growth.
EGG
The initial, organic vessel in which an embryo begins to develop before hatching.
3 Fun Ways to Use This Printable in the Classroom
Make the most of this worksheet with these creative lesson and activity ideas:
- Butterfly Life Cycle Wheel: Create a rotating paper-plate craft showing Egg -> Caterpillar -> Chrysalis -> Butterfly.
- Mealworm Observation Journal: Keep classroom darkling beetle mealworms in oats and record weekly larval molts and pupal transitions.
- Frog vs. Insect Venn Diagram: Compare complete metamorphosis in insects with metamorphosis in amphibians (gills to lungs, tail absorption).
Frequently Asked Questions
What is complete vs. incomplete metamorphosis?
Complete metamorphosis has 4 distinct stages (Egg, Larva, Pupa, Adult); incomplete metamorphosis has 3 stages (Egg, Nymph, Adult) without a pupa!
