| Duchas says that the plant on which the marsh fritillaries live will survive the development of the constructed wetlands. |
| I planted it, though, not for fritillaries but for one of their cousins, the Zebra Longwing. |
| In spring the fritillaries flower, turning the meadow into a mass of purple and white. |
| You just get this extraordinary purple haze because all the snakeshead fritillaries are out at once. |
| It is believed that some 80 per cent of the UK population of snakes head fritillaries are found at North Meadow. |
| With a similar pattern to the previous fritillaries, this butterfly is significantly smaller and has brighter orange and yellow underside. |
