This is our most important pest in the garden. It is an insect, it lives underground, grows to 8-12 or more cm length and loves all what is green. We have hundreds of them in our garden, they produce nests with hundreds of eggs and the young insects are very hungry. Last year they kill some seedling plants in my garden, but in my neighbors garden all tomatoes, potatoes, herbs ... Maybe they do like peonies so much (I hope), but to stimulate the growth of their eggs they destroy all waht is above them. (To get more sun-heating). We have some mehtods to hunt them, but so many people have asked, what is a 'Maulwurfsgrille': Here the pics. If anybody does not believe the size above, I can make pictures of adult individuals this year..
