Summary:  Scientists now know more than ever about the flies that attack monarch butterfly caterpillars, thanks to citizen science. Since 1999, volunteers participating in the Monarch Larva Monitoring Project have collected and raised more than 20,000 monarch eggs and caterpillars, and they've recorded incidents of those specimens being parasitized by fly larvae.
