Zygaena filipendulae is a medium-sized, common moth which graces gardens from as early as May in the UK, Ireland and Europe. They love Thistle and Knapweed, which they're often seen perched on in pairs- if you get our drift! They're day-flying, looking gorgeous with their shimmering black and red wings. They can easily be attracted by planting a good mixture of wildflowers. Sometimes they're mistaken for butterflies due to their behaviour when flying. They thrive in an array of habitats, including grasslands, meadows, woodland rides, hedgerows and coastal sand dunes.

Biological treatment

These caterpillars are harmless in most cases. If you spot loads on a desirable plant, remove a few using gloves and relocate. They may not be eaten by birds but serve as a yummy treat for spiders and parasitic wasps. Their eggs are a food source for other garden wildlife. You can attract them to your garden by planting Thistle abnd Birds Foot Trefoil.

Chemical treatment

It's not advised to remove these insects from the environment because they pose only a small risk to garden plants.
