More than three-quarters of the world's angiosperm plant species depend to some extent on animal-mediated pollination (Ollerton et al., 2011). Moreover, pollinators play a vital ecosystem service because they are essential for seed and fruit production of food crops (Klein et al., 2007). However, in the last decades, global change pressures (Goulson et al., 2015) such as climate change (Soroye et al., 2020) and landscape alteration (Garibaldi et al., 2011; Winfree et al., 2011) have caused pollinator declines (Bartomeus et al., 2019;Goulson et al., 2015). These global change pressures are not acting in isolation (Sala et al., 2000) and despite it is widely recognized that they might interact, few studies have explored these interactions experimentally in realistic field conditions (González-Varo et al., 2013).Most studies on the effect of global change on pollinators focus on social bees (i.e. stingless bees, bumblebees and honeybees; Colla & MacIvor, 2017;Sgolastra et al., 2019). However, bee pollinators are highly diverse, with more than 20,000 species all over the globe
