Milkweed Leaf Beetle

By William T. Hathaway

Milkweed Leaf Beetle

If you have made a close inspection of our common milkweed, it is likely that you have seen a brilliant, brassy-colored little beetle that becomes shiny-green or blue when viewed from different angles. These metallic-reflective colors account for one if its other names “The Goldsmith Beetle.” The body length of this beetle is only 8-11 cm.

Almost any student caught up in nature lore will long remember having seen this little gem of flashing color hidden among the green leaves of a milkweed or Indian hemp plant.
