Fourth instar larvae of Polyommatus icarus maintain myrmecophilous with ants. In laboratory experiments, the attractiveness of larvae reared on foliage of the tree Robinia pseudoacacia was significantly reduced compared with caterpillars fed with herbaceous Fabaceae. The ability to secrete carbohydrate-rich liquids from the dorsal nectary organ was also strongly reduced, while the function of the tentacle organs remained unaffected. The reductions in attractiveness and secretion abilities are caused by the food quality itself and not by secondary effects such as reduced larval size. The ecological significance of the results are discussed with respect to facultatively and obligately myrmecophilous lycaenids.
