Fig. 99 (next page). A. The disused "Holtug Kalkbrud" is an old limestone quarry where the small water ponds (visible in the middle of the picture) completely dry out and leave a lot of plant debris behind. By sifting this debris Teratomyces philonthi (on Gabrius breviventer), Laboulbenia flagellata (on Anchomenus dorsalis), L. leisti (on Leistus ferrugineus), Cantharomyces orientalis (on Carpelimus bilineatus and C. corticinus), and Monoicomyces homalotae (on Atheta graminicola) can be found. (Photograph: Andrea Schomann). B. By sifting this semi-fresh flood debris on the dike at Juvre in the northern part of the island Rømø in the Wadden Sea, the extremely rare Corethromyces bialowiezensis (on Tachyporus chrysomelinus) very surprisingly was found, and also Monoicomyces invisibilis (on Platystethus alutaceus) was among the species found here. The sifting of flood debris immediately after severe autumn and winter storms with large floods as a result, has proven to be extremely effective in finding large amounts of invertebrates. The picture shows evidence of no less than three such incidents, in the form of well-separated belts of flood debris consisting of large amounts of plant material on the dike. Henning Liljehult is seen here a little irresolute about where to start on a 3-kilometer-long belt of debris. (Photograph: Jan Pedersen). C. "Klintebjerg ved Klint" is a sun-exposed, sandy grazed meadow with small shallow ponds where Zodiomyces vorticellarius (on Helochares obscurus) and Chitonomyces paradoxus (on Laccophilus minutus) can be found. In cow and deer dung on the pasture Rhachomyces philonthinus (on Philonthus varians), Laboulbenia argutoris (on Pterostichus strenuus) and Monoicomyces britannicus (on Atheta longicornis) are found. (Photograph: Andrea Schomann). D. The area around the now disused railway terrain in Rødbyhavn is one of the most exciting habitats in Denmark, as for many years a completely unique flora and fauna has proved to be present. Thus, more than 30 thermophilic invertebrate species new to the Danish fauna have been found at this site. This fact is primarily due to the southern location in Denmark and a habitat type which is quite unique to Danish conditions, most of all reminiscent of the conditions on rocky or sandy pastures in Central Europe. Among other things, it is the only known Danish locality for Laboulbenia egens (on Elaphropus parvulus) which, like Rhachomyces canariensis (on Trechus obtusus), Ecteinomyces trichopterophilus (on Acrotrichis spp.), Laboulbenia calathi (on Calathus melanocephalus), L. eubradycelli (on Bradycellus caucasicus and Bradycellus csikii), L. olisthopi (on Olisthopus rotundatus), and L. pedicellata (on Bembidion illigeri), was found by sifting extremely sun-exposed dry moss and lichens on gravel. In the seed-heads of wild carrots Laboulbenia ophoni (on Ophonus puncticeps) was found. (Photograph: Jan Pedersen). E. View from part of the Wadden Sea as seen from "Rømødaemningen", where Laboulbenia giardii (on Dicheirotrichus gustavii) was found by sifting the seaweed at the foot of the dam.
