The caterpillars of this moth were found in stems of Echinochloa polystachia grass as stem borers. The length of the caterpillars are something about 1.7 cm. I have compared images from the internet for identification and it looks me similar to Diatraea saccharalis. Is this correct?
In the pictures you can see: lateral and dorsal view of the moth; caterpillar; and the pupa
It certainly looks right for Diatraea saccharalis and the species has been recorded from two different related species of Echinochloa (one from Brasil and the other from Cuba on the Natutural History Museum HOSTS website: https://www.nhm.ac.uk/our-science/data/hostplants/search/list.dsml?searchPageURL=index.dsml&Familyqtype=starts+with&Family=&PFamilyqtype=starts+with&PFamily=&Genusqtype=starts+with&Genus=Diatraea&PGenusqtype=starts+with&PGenus=Echinochloa&Speciesqtype=starts+with&Species=&PSpeciesqtype=starts+with&PSpecies=&Country=&sort=Family
