Mailing instructions: Please put about 10-20 of the largest larvae you can find (preferably fourth instars: Fig. 2), and some lily leaves into a rigid container with a lid. Please do not add any water; the lily leaves will provide some moisture. Two suggestions for good sturdy containers are cottage cheese or yogurt containers. Label the lid with your name, complete address, and the date that you collected the larvae. Please, tape container closed so that the larvae don’t escape! Include your email address and we will send you the results.
