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.

I’ve been trying to find the right name of this species. I found out that they are red bugs in different stages but what about the second picture with the pale ones? Are they adult of the same species? Thanks in advance.

Dear Brigitte,
We are very happy you provided two images because only one of the images includes winged adults and immature nymphs can be notoriously difficult to identify to the species level.  You actually correctly identified these Red Bugs in the family Pyrrhocoridae.  Bugs in this family frequently form aggregations like the one you documented.  We did a bit of searching, and we have matched the adult individuals in your photo to the Two Spotted Cotton Stainers,
Dysdercus bimaculatus, pictured on BugGuide.

Thanks, I really appreciate your help.  I’m a bird photographer and I practically know nothing about bugs.

Unknown Red Headed Bug

Unknown Red Headed Bug

Hi Frank,
Our initial attempts to identify this red headed True Bug did not prove successful, but it does remind us of a red headed Coreid Bug,
Hypselonotus atratus, that we just posted.  Perhaps one of our readers will have better luck with this one.

Karl Provides an identification
Hi Daniel and Frank:
Coreid bugs nearly always have prominent ocelli, the simple eyes on the top of the head, and much denser wing venation. This is actually a Cotton Stainer or Red Bug (Pyrrhocoridae: Pyrrhocorinae), probably Dysdercus obscuratus. The species has a very wide distribution (Texas to Peru) and is highly variable in appearance. Here is one more image posted on flickr.  Regards.  Karl

Thank you so much, Daniel! Please forward my thanks to Karl, if you have the time.
Best
Frank

just warning you Frank:  I will be away for a week and not posting.  Please don’t resume sending photos until January 22.  Your photos are quite beautiful.
Daniel

Thanks for the warning, Daniel! Have a good trip and you can count on getting more pictures from me after Jan. 22nd. You and your site are quite amazing!
Best
Frank

I’m writing from Sarasota, Florida. In June my neighbour put out some leftover dog food after her little dog died. A few days later there were all this beautiful red and black bugs in various stages crawling around it. They didn’t it the dog food, they went away from it. Even crawling up a tree. What are they?

Cotton Stainers

Cotton Stainers

Hi Ruth,
The True Bugs in the photo are immature, wingless Cotton Stainers,
Dysdercus suturellus, and winged adults.  In addition to cotton, the Cotton Stainers will also feed on other plants including hibiscus and orange trees, according to bugGuide.  Cotton Stainers, like other True Bugs, have mouths designed to pierce and suck, and it is possible that they were attracted to the moisture in the pet food. 

Hi Daniel,
Thank you so much for this information.
Have a wonderful New Year!
Ruth
