And I'm pretty sure lizards hunt them too—we had one going crazy to get through the window to 3 young caterpillars feasting away on a windowsill milkweed bouquet. “The MicroCT scan revealed how surrounding muscles may contract and relax, enabling the caterpillar to control the release and re-absorption of secretory droplets from dew patches and nectar glands that lure and sometimes deceive ants. As expected from their close relationship, the caterpillars possess all the main ant-associated organs that have been described in other obligate ant-associates, and these organs are very well developed in this species,” Associate Professor of NCBS Krushnamegh Kunte said. Dew patches, for example, operate on a ‘lasso bag’ control mechanism using surrounding muscles,” Mr. Basu said.   | Photo Credit: Unlike birds, green anoles do not hesitate to eat monarch caterpillars. They can damage the plant so severely that the hosta may die. Not only do ants not eat these caterpillars and pupae, they actually care for them and aggressively protect them from other predators and parasitoids, thus creating an enemy-free space for the butterfly’s early stages. A one-stop-shop for seeing the latest updates, and managing your preferences. Dipendra Nath Basu, a PhD student under Dr. Kunte found the problem peculiar and challenging and turned to X-ray microtomography, or MicroCT (CT-scanning is used widely in hospitals) to shed light on the functional morphology of the ant-associated organs. Although there are some caterpillars that love to munch on leaves, there are also caterpillars that prey on young ants and recently-laid eggs. The Hindu has always stood for journalism that is in the public interest. “While caterpillar-ant interactions have been explored as fine examples of multi-partner interactions, i.e. This is a crazy video of ants devouring a caterpillar.

They will stay underground during metamorphosis and will emerge from the ground as fully grown moths. Over millions of years of evolution, this butterfly group has evolved a range of adaptations that have tamed their ferocious ant predators into protectors and providers. A Moth’s Appetite The intriguing caterpillar-ant associations have been a subject of study for decades resulting in the understanding of their evolution and ecology. between caterpillars, ants and potential predators, what is important and novel about this study is the study of the mechanisms that facilitate these fascinating interactions,” said Renee Borges of the Centre for Ecological Sciences, Indian Institute of Science, an expert on plant-animal and other inter-species interactions. This experience gives me the right to say that if there are signs of insect damage, you must act rigidly without any hesitation. ), and must be eliminated where you plant but-terfly gardens to raise butterflies (see Butterfly Gardening in Texas and Landscape IPM, Butter-fly Gardening).

Once inside, the caterpillar kills and eats ant larvae while the guard ants rest calmly nearby.
