5. Why do the female wasps visit the orchid flowers? Do they have a role in pollination? The female wasps visit the orchid flowers to collect the chemical that the male wasps were attracted to earlier. The female wasps do not have a role in pollination since the flowers are dying when they visit them.
The Traveller’s palm and the Madagascar black lemur:
If the Traveller’s palm died out, the Madagascar black lemur would not die out as it can find other sources of food.
Discussion
Discuss what you think would happen to the animal pollinators of each of the plants described if these plants died out.
Suggested answers:
The yucca and the yucca moth: If yucca plants died out, the Yucca moth would also die out as the caterpillars need the yucca seeds for food.
