Some remarks on Cicindela saetigera Horn
In 1936 five specimens of the beautiful beetle Cicindela saetigera Horn (fig. 1) were collected by Prof. Dr. L. G. M. Baas Becking and Dr. J. Reuter on their journey in Australia and kindly given to the Rijksmuseum van Natuurlijke Historie at Leiden. As this rather uncommon species was new to the collections of the Museum I studied the literature on the species in more detail, especially after Prof. Baas Becking had told me a few details concerning its life conditions. Our specimens, all males, were caught at the following dates and localities: 4 specimens, March 27, 1936. Lake Bumbunga, N. from Bay St. Vincent, S. Australia. 1 specimen, April 15, 1936. Lake Crosbie, SW. from Mildura, N.W.Victoria. First of all I can state, that in most of the papers dealing with C. saetigera Horn there is an indication of the locality: Yorke's Peninsula, but no further details about the exact locality are communicated, except by Sloane (1906, p. 343) : "Wallaroo, on the shores of Spencer's Gulf". Concerning the above-mentioned localities of our specimens Prof. Baas Becking told me that he had found these beetles only on the saltlakes, where they were running and jumping on the bright white saltcrust which covers the greater part of those lakes. They prey on ants there, which live on and under the saltcrust; a rather strange habitat for insects. After Prof. Baas Becking, who investigated these saltlakes thoroughly, the beetles form an interesting link in the local food-cycle therein, which begins with the bacterial life beneath the salt-crust and ends with some lizards and birds of which no animal enemies seem to exist.
