The Holly Blue butterfly and its parasites
Extension work on Butterfly Parasitism
click here for data sheet to work from.
Holly Blue larvae were collected and reared in captivity to see how many of them hatched into healthy adults and how many produced parasitic wasps.
Use the information on this table to produce line graphs showing how the numbers have changed between 1990 and 2005, using a blue line to show the numbers of healthy Holly Blues hatching each season and a red line to show the numbers of the parasitic wasp Listrodromus nyctheremus. From summer 2004, add a green line for the other parasitic wasp Cotesia inductus.
Then answer the questions on the Parasites page.
