Plastic bottles aid butterfly conservation in Tenerife
Monarch Butterflies (Danaus plexippus) have been having a hard time of it in many areas of the world. Habitat destruction, pesticides and lack of their foodplants have all taken a heavy toll, and even pollen from genetically modified crops that has landed on Milkweed growing close by has been shown to poison the caterpillars.
Here on Tenerife in the Canary Islands, the main problem these beautiful insects face is lack of Milkweed. Unless gardeners and local councils decide to grow the plant the caterpillars have nothing to eat and the female butterflies have nothing to lay their eggs on.
