Hi
Recently moved to HK, and found this in my Hibiscus yesterday, 24 Sept. It is the tail end of summer, about 33C. About 1 inch long. We are quite close to the beach, although this bug appeared on a plant that I recently purchased and moved here from Kowloon. I have had the plant about 3 weeks.
Would love to know what it is, and if I should remove it to another plant to spare my garden. (There is a nearby undeveloped, jungley lot for the bug to emigrate to.)
Thanks

Dear Margaret,
This is a Cotton Stainer or Red Bug in the family Pyrrhocoridae and we located a matching image on FlickR that is identified as 
Dysdercus cingulatus.  We then found a reference where it is called a Hong Kong Stink Bug and the information:  “Found mating and feeding on Ipomea on September 11, 2002 at Braemar Hill, North Point, and on Hibiscus.on August 10, 2003 at Pak Tam Chung, Sai Kung, Hong Kong SAR.”  The latter link is not very accurate as the family is listed incorrectly.  It is also pictured on iNaturalist.

We identified this Red Bug on BugGuide as Scantius aegyptius.  We will attempt to capture an image tomorrow.

here’s the pictures of the bugs I found on the trunks of these trees. Some people have them in their gardens too, but I’ve never seen them anywhere else. This picture was taken at the start of the winter.

Dear Cindy,
We disagree with your identification.  We do not believe these are Soapberry Bugs in the subfamily Serinethinae, but rather Cotton Stainers  or Red Bugs in the family Pyrrhocoridae.  There are some similar looking images of Cotton Stainers in the genus
Dysdercus on ISpot and there is an image on FlickR identified as Dysdercus nigrofasciatus.  This note is also posted on ISpot:  “D. nigrofasciatus and D. fasciatus are not synonyms. There are four species of Dysdercus occurring in South Africa: fasciatus, nigrofasciatus, intermedius and superstitiosus. the first three looks superficially similar, but there are clear differences, for example: the head of fasciatus is significantly longer than the head of nigrofasciatus, etc.”  We are confident that the genus Dysdercus is correct, but we are uncertain of the species.

Dear What’s That Bug team,
Why those bugs are gathering into groups? there were quite a few of those groups.
Kind regards

Dear Slava,
These are Firebugs,
Pyrrhocoris apterus, and they are known for forming large aggregations containing both immature nymphs and adults.

Dear Charlie,
We were surprised that we received two identification requests from the British Virgin Islands on the same day, and we can’t help but to wonder if there was some local publicity that led you to our site.  For the purposes of organizing our archives, we like for each posting to contain a single species, or if there are multiple species, for them to be classified similarly.  For that reason we are only posting your “cool red beetles” which are actually St. Andrew’s Cotton Stainers,
Dysdercus andreae, a species of Red Bug in the family Pyrrhocoridae and classified as True Bugs and not Beetles.  There are several mating pairs evident in your photo.  See BugGuide for verification of our identification.  Please resend your other identification requests individually using our standard submission form by clicking the Ask What’s That Bug? link and please provide any important background information on the sightings.

Bugman, my daughter Kryss Castle and I are at Machan Paradise Resort
in Chitwan National Park. Today on an early morning jungle walk we found a Red Cotton Bug. By the way, we also saw a one-horned Rhino just 30 feet away. But we know where your heart lies!

Dear Allison,
Thanks so much for submitting your lovely photograph.  We researched Red Cotton Bug and discovered a photo on the Marc Anderson PHotography site, further identified as
 Dysdercus cingulatus, that was also taken in Chitwan National Park, Nepal, but we don’t believe that identification is entirely correct based on the images also identified as Dysdercus cingulatus on Csiro.  We do believe your bug is also in the Red Bug or Stainer Family Pyrrhocoridae along with Dysdercus cingulatus, which is substantiated by the photo of your bug entitled “Infested” by Joe Hastings on FlickR.  Continued research led us to a Red Cotton Bug on FlickR identified as Dysdercus koenigii, also from Chitwan National Park, Nepal and posted by Patrick.  We found additional examples of Dysdercus koenigii on PBase and called a Red Cotton Bug or a Silk Cotton Bug.  The Krishisewa Agriculture Information Hub of okra pests pictures an adult and nymph Red Cotton Bug, Dysdercus koenigii, and indicates:  “Life-history: The eggs are laid in clusters of 80-100 in cracks of the soil or dry leaves near the plants. The nymphs hatch out in about 7 days and become adults in 40-85 days.  The red coloured nymphs are marked by a row of 3 black spots in the middle of the abdomen and 3 white spots on either margin of it.  Damage: Both nymphs and adults suck the leaf and fruit sap. The plants become weak and stunted, the leaves and fruits may curl up.”  The black head on your individual does not appear on the nymph pictured on Krishisewa.  Project Noah calls a similar looking bug the Cotton Stainer Bug,  Dysdercus koenigii.
