I found the eggs on a twig of a plant in Rosaceae family (think some Rubus sp. but I am not sure. The place where I found them was a small neglected landscape.
The eggs were laid in two rows, 18 in total (9 on each row). It seems like the mother worked the surface of the twig before to laid the eggs.
Eggs are shaped like a bivalve shell and they are set imbricated on the row and the size of an egg is about 5 mm large and about 2.2 mm wide. The surface of the eggs is textured.
The eggs looked to be open (open somewhat like an oyster) so I thought that they are empty.
On March 29, 2019, I was surprised to see two alive nymphs in the container where I placed the eggs. Then I noticed and the remains of some (I counted two) nymphs. Cannibalism or the alive one took advantage of the dead brothers and ate them.
The size of the body nymphs: around 3.5 mm.
