Abstract: Platytomus tibialis (Fabricius, 1798) is mainly spread throughout the whole Mediterranean area. Biological observations were made in Southern France, in a site situated along the Rhone river. From September to May, adulta remained in the soil, and their activity was reduced. Beetles were mostly active at the end of spring and in summer, and they were found at this moment under animal droppings (horses, but also cattle and sheep), where they searched for humidity. Mating and oviposition occurred in soil, consisting in a foliated mixture of sand, silt and compost. Larval development required one month. The fist description of the larva of a species of the genus Platytomus Mulsant, 1842 is given. Larval morphological characters are very similar to those in the genus Pleurophorus Mulsant, 1842 of the same subtribe Rhyssemina, sensu Pittino & Mariani (1986). |
