THE LOVELY LOVE BUG

This interesting plant bug with the heart on its back ...

... is the Lygus pratensis ... a sap-sucking species. Both the nymph and the adults suck the juice of different herbaceous plants.
The females lay their eggs in May and June in flower buds or other plant parts. The tiny eggs are round and white and are deposited in groups. The nymphs initially are small, round and bright. In the later stages they are completely green, and they can easily be confused with aphids.
As always, the photograph is my work.
