Abstract
Surveyed ISTHA roadside vegetation management areas at 29 points along I-90 and I-88
• Most sites contained milkweed plants, usually Common Milkweed (Asclepias syriaca)
• No Monarch adults or larvae observed during sampling
• Other butterfly, beetle, bee, and wasp species were observed
• The 5 sites with the highest overall scores were in the I-90 corridor
• The I-90 corridor sites tended to have more nectar and invasive species than those in the I-88 corridor
• Invasive species were a threat at all sites
