Distribution: Found on islands of the Caribbean basin and of the Lesser Antilles, as well as in the Florida Keys.
Habitat: Usually found where one of its hosts appears, such as cotton plants or Portia trees. Usually live in tropical areas around coastal woodlands and cotton plantations.
Diet: Mainly feed on the seeds of host plants, but will occasionally feed on unripened fruit.
Description: St. Andrew's Cotton Stainer is named so for two reasons, the first being the white "X" present on its back, resembling the cross on the Scottish flag. Its feeding habits tend to leave yellow-brown stains on cotton bolls, which cannot be washed out and thus affects the quality of the cotton, thus the nickname "cotton stainer".
Cotton stainers as a whole are considered fairly important pests of cotton plantations, both for their staining habits but also because their presence can limit the growth of cotton bolls, reducing yield during harvest, but also because they damage fruit.

@panaceaphantastica submitted: Hi I'm sorry for adding my face to the mix but I couldn't help but laugh when I saw this picture my boyfriend took of me excited about a pretty bug I found. Literally seconds before I started asking for the camera so I could take a picture to submit it here! Ur allowed to post this submission btw if me being in it is not against the rules! Took while climbing at the Brazilian Highlands, Itatiaia National Park, Minas Gerais, Brazil. I would love to know what kind of bug is this, there was this one time when I was 6 or 7 that I found (to my horror) three of these in my pants somehow???? They were just sitting there and I spent the day with those pants and only noticed something weird at night. Still feels like a fever dream.
(I think I accidentally deleted the auto tags I'm so sorry I hope this doesn't mess anything up)
Nope, it doesn't mess anything up, I can easily re-add the tags. They're just there so I don't have to type them every single time.
Anyhoo I too would get excited about this little dude! Very colorful. It's a cotton stainer bug, Dysdercus ruficollis. They're a type of plant bug, so definitely harmless to people. Not sure what they were doing in your pants lol. Human taxi?
Red means danger...to those birds who might snack on a bug. Meet Dysdercus ocreatus a "cotton stainer" or, if you will "redbug" feeder on plant juices and found on cotton plants, messing things up. This one was found in the Dominican Republic - Common on flowers ; identified by Tom Henry
