In North America, a toxic weed called leafy spurge was accidentally introduced and has grown and spread rapidly, covering millions of acres in north central United States and south central Canada. Leafy spurge is generally avoided by cattle and horses and may be toxic to them. Thus, rangeland where leafy spurge has spread has been damaged by the invasion of this plant. Many strategies have been used to control leafy spurge, including the deliberate introduction of different species of flea beetles that feed on leafy spurge. Each flea beetle female may lay about 200 eggs in her one-year life span. If the flea beetle population doesn't actually eat the leafy spurge, and reproduces enough to become a nuissance, what might happen?
Select one:
a. The flea bettle stays within its tolerance zone in the local environment
b. The flea beetle becomes an economic success and eliminated leafy spurge
c. The flea beetle can become an invasive species
d. Local insects keep the flea beetle in check
