Palomena prasina with berry-belly(?) Inspired by a comment exchange with Christine I dug up some old images of a discussion about food possibly influencing the colour on the belly of this Green shield bug. I&#039;m a bit dismayed at the poor quality of the old photos (all between 2006-2008), but they still show the cause for discussion/doubt, so hey ...<br />
<br />
When I found this here bug (photograph above), I was convinced the pink belly would have been caused by the diet of reddish-purple berries it was sitting on. The colours just seem to match perfectly.<br />
<br />
This image was taken on September 3rd. We had a short discussion on this on waarneming.nl (a Dutch biodiversity platform) and it was suggested that the colour could very well be &quot;just&quot; the beginning of this animal&#039;s change to winter colours.<br />
Indeed, in this process the belly usually seems to &quot;go&quot; first with many brown &quot;freckles&quot; appearing, just around the same time in September. To illustrate this, here are two images of September 10th and 18th both from a different location than the one above, where there are no red berries present, so in this case the colour is the onset of winter colouring, I&#039;m sure.<br />

September 10th, this one is already changing to winter dress:<br />

All in all, I still think the pink on the first image matches too darn well with the berries, but given that this was in September and these critters do start getting brownish speckled bellies around that time I can&#039;t be sure ... possibly still a combination of the two?!?

Palomena prasina with berry-belly(?)

Indeed, in this process the belly usually seems to "go" first with many brown "freckles" appearing, just around the same time in September. To illustrate this, here are two images of September 10th and 18th both from a different location than the one above, where there are no red berries present, so in this case the colour is the onset of winter colouring, I'm sure.

  1. So fascinating! The belly really is so pink. The intensity of a creature's color is often influenced by diet, so maybe the berries did have an impact, in this instance. Posted one month ago

The green shield bug is a shield bug of the family Pentatomidae. It may also be referred to as a green stink bug, particularly outside of Britain, although the name green stink bug more appropriately belongs to the larger North American stink bug, ''Acrosternum hilare''. The adult green shield bug ranges in the colour of their backs from bright green to bronze, without any substantial markings. Green shield bugs are a very common shield bug throughout Europe, including the British Isles, and are.. more
