Nesting biology of Hoplitis (Tkalcua) zandeni uncovered

The biology of the two Hoplitis species of the subgenus Tkalcua was entirely unknown so far. On their excursion to Fuerteventura in spring 2015, V. Mauss and A. Müller detected nests of H. (Tkalcua) zandeni in empty snail shells. For details see the species account on the Palaearctic osmiine bee website.
