Sweet Potato Flea Beetle
A minute, shiny bronze-black flea beetle with enlarged hind legs for jumping. It creates linear feeding tracks in sweet potato tubers, reducing their market quality.
Did You Know?
Larvae tunnel into sweet potato tubers creating winding tracks just under the skin, causing cosmetic damage that significantly reduces marketable yield.
Spruce Beetle
A dark brown to black bark beetle that is the primary killer of mature spruce trees in North America. Outbreaks are triggered by drought, windthrow, or warming temperatures.
Did You Know?
A single outbreak in Alaska during the 1990s killed spruce trees across more than one million acres.
