I sweeping the grass with a net in attempt to catch something else. But I caught only this one :) Almost pupa (!?) ... I was not able to see it well on the field). In vial it attached with silk on vial wall and it was definitely a pupa and in 5 days (or a little less - 4 days) it changed in moth.
So most probably was on grass, but not quite sure because was some weed around, too. Mainly other weeds in the area are Parthenium hysterophorus (Asteraceae family) - an invasive plant native to American tropics, but there are some Malvastrum coromandelianum (Malvaceae Family) and less others weeds.

Very interesting and I think necessary for the Guide. Amazing that it was not damaged in the process and explains that it is a pupa since it is so different from the caterpillars in the guide. Maybe other understood, but I did not. Thanks.

The photo of moth was shoot with the camera very close to the subject.
When I saw first time in vial the moth had some kind of green. But the plastic vial wall filter the light. This moth was not very cooperative to photograph. But it accept to stay on vial lid, which is like white (never can be sure). In the time o shooting I kept close the vial to catch the moth in the case if would try to fly.
Now I tried to look to the moth outside in day light (but it is cloudy). Unfortunately I escape the moth without to see very well the colors. Anyway I did not have the intention to keep it. It seems to have some green but not so light.
I attached two more photos. The first is the same but different edit, the colors seems to look better but in exchange is lost some of details clarity. The second is another photo took with the camere a little more far from subject. (Keeping the camera very close to subject involve some shadows) Which one do you think is better to be kept?

Other photos on BG show it with a greenish hue. Not to worry, the pupa nails the ID.
