Common green shieldbugs like these overwinter as adults so it’s not that they’ve just hatched out but rather that the warmer temperatures and, some days, actual sunshine combine to tempt them out of these cosy hideaways under leaf litter or in cracks in bark.

As you can see, these shieldbugs (scientific name Palomena prasina) aren’t always true to their name. During the winter months, their colour turns more brownish. It’s during the summer months that they can be seen wearing their true, bright green livery.
