Weeds benificial to native fauna ?

It Has been my observation that certain weeds namely Oxeye daisy (Leucanthemum vulgare) Wild carrot (Daucus carota) and Calla lilly (Zantedschia aethiopica) are eagerly sought out and extensively utilised as nectar / pollen sources by both native and introduced invertebrates
Where these weeds follow streams (Adequate light) into native bush (Usually secondary growth as mature native bush tends to meet in the middle above streams) the percentage of native species far exceeds introduced species. Where these weeds are found in the midst of Dairy farms or other highly modified environments the reverse applies. I believe this gives the native species a much needed energy boost at a time when they most need it (Spring / Summer breeding). Also the large numbers / species of nectar / pollen feeders inevitably attracts a large number / species of predators again both native and introduced. My theory is that these particular weeds (And no doubt many others) are beneficial to fauna even if detrimental to flora.
