In May 2011 we noticed high number of Podagrica fuscicornis adults on the leaves of common marshmallow (Althaea officinalis) grown on Laboratory Field of Biotechnical Faculty in Ljubljana. In Slovenia, this beetle was already recorded earlier but it did not caused any damage on common marshmallow (Althaea officinalis). Due to the feeding of beetles on leaves, 1 to 2 mm large holes appear. By expecting climate changes, already known bionomics of some related species and giving more emphasis on herb production in the future, Chrysomelid P. fuscicornis might represent medium sized biological factor in producing common marshmallow. V maju 2011 smo na listih navadnega sleza (Althaea officinalis) na Laboratorijskem polju Biotehniške fakultete v Ljubljani ugotovili večje število odraslih osebkov bolhača Podagrica fuscicornis. Vrsta je bila v Sloveniji že prej zastopana, a ni bila škodljiva pri pridelovanju navadnega sleza (Althaea officinalis). Na listih rastlin se kot posledica hranjenja hroščev pojavijo 1-2 mm velike luknjice. Ob pričakovanih podnebnih spremembah, znani bionomiji nekaterih sorodnih vrst in večjem pomenu pridelave zelišč v Sloveniji bi lahko vrsta P. fuscicornis v prihodnosti bila srednje pomemben biotični dejavnik pri pridelavi navadnega sleza.
