Cairns Botanical Garden
The route Cools takes you on through the Cairns Botanical Garden is the walk he first made when exploring the garden for host plants for butteries. This first inventory provides a picture of the butterfly species possibly present at the botanical garden. A host plant is a plant caterpillars eat once hatched. Many butterflies have only one type of host plant; without this, the butterfly cannot reproduce. To continue his research on meconium, Cools uses this inventory of the garden's host plants and related butterfly species so that, throughout his research period at the gardens, he can investigate whether indeed caterpillars emerge on the host plants.
