There's a two native lungworts Pulmonaria longifolia & Pulmonaria obscure plus the common Pulmonaria officinalis which is thought of as native though introduced, mine flowers in December and are only just finishing. More suggestions: Alyssum, Ivy, Dandelion are really good, clover, Aubrieta, Grape Hyacinths, Ajuga repens, Aquilegia vulgaris, Berberis, Caltha palustris, heather, Basically any species plant that flowers will have evolved to attract pollinators. So if it's not a species and you don't know it's fertile then stay clear of it. I would go native every single time and that way you'll stand a very good chance of feeding larvae too. After all no larvae, no adults. Here's a list of native plants and a list of food plants. I know you're asking for earlies but if you look out for what's flowering at the period of interest and then go only for the un-named species form then you won't go far wrong.
Our field are full of Lady's Smock at the moment. Jim
Yeah, such a lovely flower too. I've had to introduce it to my garden despite it growing in profusion in the meadows just a mile away and I've even spotted it up the road by the post box.
