The garden is full of hoverflies at the moment and not least amongst the favoured flowers for these visitors are the Hostas. This one is called ‘dream queen’ which has much thicker leaves, theoretically less attractive to slugs.

Note from Urban Pollinators blog:
“Most hoverflies visit flowers for nectar but some hoverflies such as some Melanostoma spp., Syrphus spp. and Episyrphus balteatus (Marmalade hoverfly) are specialised pollen feeders and often visit flowers just to feed on the pollen“
