Animal migration: seasonal reversals of migrant moths.
A recent study has found that, as migrating silver Y moths pass high overhead above central England in the spring, their headings were generally aimed towards north---a reversal of direction relative to that of autumn migrants. The silver Y must detect its direction of movement, likely by a magnetic sense which must reverse with the season.
