The Megacrania batesii insects live in plants that grow where?
Megacrania batesii The peppermint stick insect ("Megacrania batesii") is a bluish-green coloured stick insect that only lives on the midribs of the leaves of the "screwpine" "Pandanus tectorius". If disturbed during the day, it emits a fine spray of a milky substance with an odor resembling peppermint. They do not use their hindlegs for locomotion.
Vachellia collinsii Vachellia collinsii is a species of flowering plant. It grows in secondary succession in seasonally dry ecosystems in southern Central America, where it exhibits a symbiotic relationship with several species of ant ("Pseudomyrmex spinicola", "Pseudomyrmex ferruginea"). The ant-"Vachellia" system involving this species has been studied by ecologists like Daniel Janzen in Palo Verde National Park and Santa Rosa National Park, both in Guanacaste Province, Costa Rica. The ants chew holes in the tips of the hollow stipular thorns, known as domatia, so that they can enter, and create their colony inside. A single ant colony may span several "V. collinsii" trees.
