The Ten-lined June Beetle (AKA the watermelon beetle) is a relatively long-lived insect, with its larval form lasting up to four years! The grubs live within the top 14 inches of soil, consuming the roots of plants. As adults, they emerge to eat leaves and find a mate. They can be found in the western part of the United States and Canada. Keep your eyes peeled for these awkward insects from dusk to about midnight on summer evenings.
