As mentioned in the article, Angiosperms emerge in the fossil record later than this butterfly-like lacewing. The earliest flowering plants had flowers that are thought to be pollinated by beetles. Wind pollination evolved several times in flowering plants, with plants that are now wind pollinated arising from plants that had flowers that were larger and had characteristics associated with attracting insects. There are extant "primative" plants without flowers that are pollinated by insects (many more in the fossil record). A great example is Gnetum, which is a gymnosperm (more specifically, a Gnetophyte). It's likely that pollinators like the lacewing in the article came first, and flowers came afterwards.
