Though it is pale in color, we believe this is a Red Bug in the family Pyrrhocoridae.  Here is a similar looking individual from TrekNature.

Mediterranean Red Bug

Mediterranean Red Bug

Dear Ken,
The Mediterranean Red Bug,
Scantius aegyptius, is an invasive species that was accidentally introduced into Southern California recently.  We first found an individual in our Mount Washington, Los Angeles office grounds two years ago, but luckily we have not found another.  According to BugGuide:  “native to the Mediterranean, adventive in NA (first found 2009); established in so. CA.”  According to the Center for Invasive Species Research:  “Recently, another brightly colored, mostly seed feeding bug belonging to the family Pyrrhocoridae or ‘Red Bugs’ has become established in southern California and is drawing attention due to large aggregations of the bright red and black nymphs and adults feeding on annual broadleaf weeds in open space areas.  Scantius aegyptius, an old world pyrrhocorid bug, native to the eastern Mediterranean region, was documented for the first time in North America in Orange County during June of 2009.  Reports of this insect from other southern California locations (i.e., Riverside County) suggest that this insect has been established for a year or more prior to these Orange County collections.”  The site also states:  “Damage: The literature contains very little information regarding the biology of S. aegyptius and Scantius species in general are not considered to be economically important species.  In California, Scantius has been observed feeding on the developing seeds and stems of Knotweed (Polygonum spp.) and Malva (Malva parviflora).  It is likely that S. aegyptius will feed on the seeds of several species of annual herbaceous plants.  The most noticeable impact of S. aegyptius in California will likely be the presence of large numbers of nymphs and adults migrating from drying annual weeds into adjacent developed areas.  These migrations consisting of thousands of individuals can be very conspicuous and lead to large aggregations on small patches of host plants causing concern to local residents who notice these obvious aggregations.”

Big man,
I was in Mozambique Africa June 10-15 this year and saw this bug. It was about 1/2 an inch long maybe more. We were driving from Tofo to Beliene and stopped on the side of the road. I thought it looked interesting and took a picture. Do you know what it might be?

Dear Liz,
Our suspicion that this is an immature Red Bug in the family Pyrrhocoridae was confirmed when we located this matching image on iNaturalist, but alas, it is not identified to the species level.

Hi, we live in Kempton Park and have noticed on our pavement trees these red bugs. Can you please advise what they are and if they are problematic to surrounding areas. They are on the tree trunks and in the grass at the Base of the tree. Thank you.

Dear Tracy,
Judging by the mating pair in the center of your image, there will soon be even more Red Bugs at the base of this tree.  They really are Red Bugs in the family Pyrrhocoridae, and thanks to iSpot, we have identified them as Cotton Stainers,
Dysdercus fasciatus. Though they are aggregating on the trees, we do not believe they are damaging the trees.  They may be feeding on the seeds of the trees, like the individuals in this iSpot image.

Thank you for taking the time out to have a look like this.

This bug was rolling what looked like a small ball of dirt or dung very efficiently- almost dribbling it like a soccer ball.
Many of them were huddled in clusters. It was the afternoon on a dirt road.

Immature Red Bug

Dear Cilan,
This is an immature Red Bug in the family Pyrrhocoridae, and it looks like this image posted to FlickR.  We suspect the ball is actually a seed and the Red Bug is feeding from the seed.  Like other insects in the order Hemiptera, the mouth is designed for piercing and sucking.

Help! I have a plague of these red beetley insects coming into my new apartment. There are about 30+ that have entered. They fly and they seem drawn to people. I live in the Dominican Republic in a new apartment building surrounded by sugarcane farms. It’s sugar cane harvest season right now and they’re burning a lot of the fields. Help! I need to know how to keep them out of my house!

Hi Grace,
This is a St Andrews Cotton Stainer,
Dysdercus andreae, and you can find out more information on American Insects where it states:  “In the West Indies this species develops on the seeds of the Portia tree (Thespesia populnea), a member of the mallow family that grows along the shoreline. The bugs can also develop on cotton, and in fact Dr. Harold Grau and his associates at Christopher Newport University have demonstrated that the species grows larger on cotton than on Thespesia populnea.”
