Collecting Report for 2002, February to 5-24-2002
|
|
| |
|
| Over
all collecting in Southern California has been pretty dismal.
The continuing drought conditions here have made collecting
a very hit or miss situation, even areas which in general look
rather promising have proven to be disappointing. |

USA California Riverside Co.:
Palm springs
Linepithema humile Mayr
Solenopsis invicta Buren
Leptothorax rugatulatus Emery
Both S. invicta and L.
humile are apparently very well established in the area,
any locality that had access to irrigation, i.e.: watered
lawns had at least on of these two species. L. rugatulatus
is represented by one specimen and apparently represents
an introduction to the area as well due to agriculture.

July 2002
USA Arizona,Cochise County
Whetsone Mountains, French Joe Canyon
Due to car trouble, what was
meant to be a week in
Arizona ended up only being a couple of days. The
monsoons had been fairly consistent over the last couple
of weeks so there were high hopes for a fair amount of
species diversity.
French Joe Canyon is one of
those places that everyone seems to pass on their way to someplace
else, this is too bad as the location is a fairly user friendly
and diverse area. It is a fairly popular location for bird
watchers, and this weekend was no exception. Recent sightings
of a "Brown Headed Warbler" had the "birders"
out enmasse.
The drive into the area was
promising, although there was little greening evident, recent
rain had left numerous puddles.
Upon arrival at the parking
area, a quick tour indicated a large amount of ant activity.
It was obvious that nuptial flights had been going on for
several days, and in fact were still going on.
One of the most readily apparent fliers was Myrmecocystus
mendax, There were numerous colonies in the area, all
of which had sexuals waiting to fly.
