I was walking my dog on a path by the ocean and noticed a large isolated collection of bright red bugs I don’t recall ever seeing in my life despite living in this general area all my life.

Aggregation of Mediterranean Red Bugs

Dear curious dog walker,
These are Mediterranean Red Bugs, an invasive species that was recently introduced to Southern California.  They generally get noticed when they form large aggregations of both adult and immature individuals.

Cotton Stainer

Dear Lynne,
This is not a Beetle, but rather a True Bug.  This is a Cotton Stainer in the genus
Dysdercus, and we believe it is Dysdercus sanguinarius based on this En Advisor Travel site.

Dear Daniel
Many thanks  – that is brilliant and so quick too!
The fact it is not a beetle explains why my attempts to ID it failed miserably!
Best wishes
Lynne

Cotton Stainer from India

Cotton Stainer from India

Dear Aditi,
The reason you have had trouble identifying this Cotton Stainer,
Dysdercus cingulatus, is because it is a True Bug in the Red Bug family Pyrrhocoridae, and not a beetle.  The Cotton Stainer is pictured on Biodiversity IndiaCurrent Biotica has a scholarly article that states:  “The red cotton bug, Dysdercus cingulatus Fab is an important pest damaging okra in India. Both adults and nymphs feed on developing fruits and affect the crop yield and quality of fruits.”  As an aside, we are fascinated that the city Noida is an anagram for India.

Dear Daniel,
Thanks so much,is it also called ‘Red Cotton Bug’ ?

That is correct.

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.”
