Ragwort hosted a colony of Black
Ants which were probably attracted by
jacobaeae. The aphids are usually
attended by ants which may build earth tents over them.

is a alien hybrid ragwort first introduced to
into the UK around 1690
via the Oxford Botanic Gardens. It escaped into the wild and spread rapidly
along railway tracks from the late 19th century.
In Shoreham it favours the gravel ballast of the railway track (near Eastern
Avenue Railway Level Crossing) and areas of shingle on Shoreham
Beach. Its flowers are a richer
yellow than the native Common Ragwort
and Hoary Ragwort.
It is a more attractive plant with a longer flowering season. It
can be seen in flower from April until November. The small and weedy Groundsel
still flowering in Old Shoreham.

Common Ragwort & Hoary Ragwort
Ragwort, the outer phyllaries under the flowerhead
should be about half as long as the inner, which have green rather than
dark tips. That all seems to be the case here. The late flowering is persuasive
as well, though not conclusive. The leaves would clinch it further, but
I'd be happy with Hoary.

Ragwort on Shoreham
On Mill Hill, south of the Reservoir I spotted my first two Cinnabar Moths of the year. They were easily disturbed and flew through the long grasses and stems of Greater Knapweed quite quickly, and too elusive for a tired photographer as I was about to leave Mill Hill.
By the Reservoir on Mill Hill the first Cinnabar Moth caterpillars of the year were seen on a small clump of Ragwort.
Hoary Ragwort was in flower on the Coastal Link Cyclepath south of the Toll Bridge, Old Shoreham.
Only the phyllary bracts are black tipped in the Common Ragwort and some Groundsels.
other green leaved species is the alien known as the Oxford
squalidus. All bracts
are black-tipped in this species.
