busyOn the downside, this means people shouldn't try to raise wild eggs or caterpillars for release. It doesn't increase the rate of successful migration.
On the upside, this tells us something vital and subtle about how migration and navigation work in monarchs. Followup studies may be able to determine what that instinct is, how and when it develops, what disrupts it, and so on. This could explain why the migration is failing so badly. It may not just be habitat loss -- if something is screwing up navigation, we need to know what so we can stop doing it.
