Tropical Paper Wasp

A very interesting observation I could carry out in my wild garden, when they decided to use a succulent plant's spike to hang their nest on. Nests are built of chewed plant material, have multiple rooms and after laying one egg in each room, plus chewed caterpillar as food, they close each chamber. It started with four wasps, hence my macro shots, but later there were about 20 of them, some a bit aggressive, defending the nest, so that kept me on distance, using a tele to get the shots of the extended nest.
Males have one band on the last part of the abdomen, females have two. The females also have brown eyes whereas the males have black eyes.
The time between the first photo and the last (L to R) is six weeks
