spotted cucumber beetle and its larva, the southern corn rootworm (''D. undecimpunctata''), the
cucurbit beetle (''D. speciosa''), the
banded cucumber beetle (''D. balteata''), the
northern corn rootworm (''D. barberi''), the
striped cucumber beetle (''A. vittatum''), and the
western striped cucumber beetle (''A. trivittatum'').
The insects live about eight weeks, during which time both larva and adult feed on plants. Adults will attack the tender young growth of stems and leaves, and the buds and petals on mature specimens. They also carry and spread the
bacterial wilt organism ''
Erwinia tracheiphila'' and the
cucumber mosaic virus. Eggs are laid in clusters on the undersides of host leaves and hatch into larvae long. The larvae often tunnel into the soil to attack roots.
