Large rose sawflies insert their eggs into new rose shoots. When the eggs hatch, the larvae eat in groups, as in this photograph – they can get through a lot of rose leaf in a short time!

In the Old Pond Garden, large rose sawflies particularly enjoy the Rosa glauca in Bed Q, which is a rose with blue-green leaves, reddish stems and bright pink flowers.

Watch a sawfly eating a rose leaf – chomp chomp chomp!


Find all the Bugs in the Old Pond Garden (there are ten altogether), put the letters together and find the final Bug!
If you spot any real live bugs / creatures / insects in the Old Pond Garden today, try to take a photograph and find out what it is. We’d love to see it, so if you post on Instagram you can tag us: @cabahs_hortisoc and use the hashtag #BugsInTheBeds
