An idea to save Mexico’s oyamel forests could help monarch butterflies too
Climate change is putting monarch butterflies’ overwintering forests in Mexico at risk. Could planting new forests solve that problem?

The last leg of the longest butterfly migration has now been identified
After a long journey across the Sahara, painted lady butterflies from Europe set up camp in central Africa to wait out winter and breed.

Big monarch caterpillars don’t avoid toxic milkweed goo. They binge on it
Instead of nipping milkweed to drain the plants’ defensive sap, older monarch caterpillars may seek the toxic sap. Lab larvae guzzled it from a pipette.
