The feeding strategy of filtering suspended particles from the water was developed earlier in aquatic insects than previously assumed. This was revealed in a study on fossil insect larvae from the 245-million-year-old Grès à Voltzia sandstone of the Vosges Mountains by Dr. Arnold Staniczek, specialist on aquatic insects at the State Museum of Natural History in Stuttgart, and his colleague Dr. Pavel Sroka from the Czech Academy of Sciences in České Budějovice.
