Yellow horned-poppy
Easily recognised in its beach habitat, the Yellow horned-poppy is so-named for its long, curving seedpods that look like horns! Look for golden-yellow flowers in June.
Yellow iris
The large, sunshine-yellow flowers of the yellow iris brighten up the margins of our waterways, ponds, wet woods, fens and marshes. Also called the 'flag iris', its outer petals have a characteristic 'droop'.
Yellow meadow ant
The yellow meadow ant is known for creating anthills in grassland habitats. It has a close relationship with the Chalkhill blue butterfly - protecting the larvae in return for a sugary substance they secrete.
Yellow slug
The Yellow slug lives up to its name - its yellow body is mottled with grey patches. Often found in gardens and damp places in houses, it can be considered a pest, but is an important nutrient recycler.
Yellow star-of-Bethlehem
The Yellow star-of-Bethlehem is a woodland plant that lives up to its name - it displays starry, gold flowers in an umbrella-like cluster in early spring.
Yellow wagtail
The yellow wagtail can be spotted running about, chasing insects on lowland damp marshes and meadows during summer. As its name suggests, it does wag its tail!
Yellow water-lily
Look for the Yellow water-lily in still and slow-moving water, such as ponds, ditches, lakes and canals. Its lily pads and cupped, yellow flowers float at the water's surface.
Yellow-browed warbler
This charming little warbler is an increasingly common sight in autumn, when migrants pass through the UK.
Yellow-rattle
Brush through a wildflower meadow at the height of summer and you'll hear the tiny seeds of yellow-rattle rattling in their brown pods, hence its name.
Yellow-tail
This snowy white moth is easily mistaken for the similar brown-tail, until it lifts its abdomen to reveal a burst of golden-yellow.
Yellow-wort
A plant of chalk and limestone grasslands and sand dunes, Yellow-wort has butter-yellow flowers. Its distinctive leaves sit opposite each other, but are fused together around the stem.
Yellowhammer
Like many of our farmland birds, the yellowhammer has declined in number in recent years. Spot this bright yellow bird singing from the top of a bush or fence, or in a mixed-species flock in winter.
