Migration of chemical elements in food chains and ontogeny phases of meadow moth in the remote migration of butterflies

To study the complex problem of the remote migrations of insects SR XRF analysis seems to be most promising. It provides fast and exact determination of elemental composition of biosamples. The presence-absence of "marking" elements and groups of elements allows one to identify geographical populations (origin) of insects. This work is based on the planned and specially performed laboratory experiments which should answer the questions on assimilation of different chemical elements, migration of these elements atontogeny phases and accumulation or the release of some elements at the final developmental stages.
