Dear all, my colleague Pavel Láska asked me to inform you all that his friend Jindra Dušek died in Saturday 26. September 2009. Pavel Láska worked with Jindra Dušek on Syrphidae for many years. They published in tandem (Dušek & Láska) about 27 papers on Syrphidae. I think that all know Dušek's figures of Syrphidae larvae. Libor Mazánek
