Biology

Species belonging to the I. incertus species-group are gall-makers and oviposit before pollination, while I. flavicollis species-group species oviposit at the same time as pollinators. The species belonging to the I. carme species-group species oviposit after pollination and are cleptoparasites and may feed on pollinator larvae (Elias et al. 89 2008; Elias et al. 2012; Farache et al. 2017).
