Insect populations including butterflies are declining worldwide, and they are becoming an
urgent conservation priority in many regions. Understanding which butterfly species migrate …

Every fall, millions of North American monarch butterflies undergo a stunning long-distance
migration to reach their overwintering grounds in Mexico. Migration allows the butterflies to …

Moths and other insects are attracted by artificial light sources. This flight-to-light behaviour
disrupts their general activity focused on finding resources, such as mating partners, and …

Migration independently evolved numerous times in animals, with a myriad of ecological
and evolutionary implications. In fishes, perhaps the most extreme form of migration is …

Monarch butterflies are known for their spectacular annual migration in eastern North
America, with millions of monarchs flying up to 4,500 km to overwintering sites in central …

Dispersal represents a key life-history trait with several implications for the fitness of
organisms, population dynamics and resilience, local adaptation, meta-population …

Migratory animals exhibit traits that allow them to exploit seasonally variable habitats. In
environments where migration is no longer beneficial, such as oceanic islands, migration …

For many animals and insects that are experiencing dramatic population declines, the only
recourse for conservationists is captive rearing. To ensure success, reared individuals …

In many species, migration can increase parasite burdens or diversity as hosts move
between diverse habitats with different parasite assemblages. On the other hand, migration …

Hydrogen isotope geolocation of insects is based on the assumption that the chitin in the
wings of adult migratory insects preserves the hydrogen isotope composition (δ 2H) of the …
