Digging for AnswersKnow Your Butterflies
Butterflies are truly one of the most amazing insects on the planet. They go through four stages of transformation, otherwise known as metamorphosis: egg, caterpillar (larva), chrysalis (pupa), and adult winged butterfly. From country to country, state to state, and county to county, butterflies vary. If you're planning on creating a butterfly garden, it's good to know a few things before you get started.
Butterflies of Illinois
There are more than 90 butterfly species in Illinois. Identifying these beautiful pollinators will help you determine the plants you'll need in your garden. Butterfly species such as black swallowtails (Papilio polyxenes aterius Stoll), Eastern tailed-blues (Everes comyntas Godart), monarchs (Danaus plexippus Linnaeus) and American painted ladies (Vanessa virginiensis Drury), can be seen in more densely populated areas and cities in Illinois.
Different Food for Different Stages
Two of the stages—caterpillar and adult—are the insects' primary feeding stages. Caterpillars usually require leaves, and adults require nectar. Here are just a few species of butterflies found in Illinois, and what they eat, when:
