hi Sugian, can you please supply a reference you used for the species identification?
I've checked a lot of photos of this claimed species and it seems it has quite a variable appearance. I'd say the species is very likely correct, but just want to double check. Posted 7 years ago

  Dysdercus decussatus is not that variable but there are some misidentified photos. There are two forms - with black or red head. The nymphs can be more tricky to identify so the best way is to have an adult around. They should have a black head so this may be a Dysdercus cingulatus nymph which is also similar and has a red head. However, they usually have some white spots on the upper side so I am not sure.

      Yes - not decussatus for sure, but I have some older images of Dysdercus from Indonesia that I never dared to ID with certainty :o(

      The nymph was found together with one of the adults and it is very similar to the photo above:

      I remember that there were some issues in keying out my adults to cingulatus s.str. so I've left it at "Dysdercus cingulatus-Group"
