What's That Bug? does not endorse extermination

Pale Red Bugs Mating

Id help needed – pretty bugs!
November 21, 2009
I photographed these bugs on butterfly holiday in the USA in Nov 2006. There were seen at the Westlaco Valley Nature reserve in the Lower Rio Grande Valley, Texas. As I live in England I don’t have any suitable field guides and wondered if someone can Id these for me.

Pale Red Bugs Mating

Hi Maris,
This is a new species for our website, but we quickly identified your mating Pale Red Bugs or Turk’s Cap Bugs, Dysdercus concinnus, on BugGuide.  The Rio Grande Valley in Texas is the northernmost reach of the range of the species which is found in Central America south to Columbia.

red bug taking over my yard
October 10, 2009
This bug is invading my yard. They are multipiling like crazy. So far they are just eating weeds. But what happens when they run out. I have chickens they wont eat them, and for that reason Idont want to use poisons. I believe this is a new bug to this area and I think its going to take over.

Red Bug Aggregation

Red Bug Aggregation

Hi Kim,
Interestingly, these really are Red Bugs.  The species, Scantius aegyptius, is not native, and according to BugGuide, has only been reported from California.  It does not have a common name, but is in the family Pyrrhocoridae, the Red Bugs.  The UC Riverside Website lists its origin as the Mediterranean.  The UC Riverside Website states:  “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 website also indicates:  “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.
