...by the way.. "NecDew" refers to "nectar" (produced by plants) and "honeydew" (produced by sap-sucking insects, such as aphids and scales). NecDew is a nectar and honeydew mimic. Ants LOVE this stuff!!
(NecDew is a "bait matrix". There is nothing toxic in NecDew. Various toxicants can be added to make it toxic to ants.)
In 2002, articles about NecDew appeared in 2 magazines and several newspapers around Florida, for example:
"Featured Creature" article. This ant has been causing lots of problems on Florida's East Coast, especially around
West Palm Beach... (sometimes called a "brown crazy ant").
!!!!! August 2006: I found an infestation in Boca Raton!!!!!
Camponotus floridanus and C. tortuganus

Non-technical with PHOTOS OF WHITE-FOOTED ANTS
(Numerous other newspapers and magazines carried this story)
I went on my second Baha'i Pilgrimage 2-10 February, 2004. This is one out of over 600 photos that I took.
Click (above) on "The Baha'i Faith" or the new international website "Baha'u'llah" to learn what this is all about...

Question for "scientists"
Could a true scientist go through life and miss the most significant event in human history even though the signs are right in front of him?
An excellent novel by
F.P. Grove (1947) Consider Her Ways
Florida Wax Scale (Ceroplastes sp.) killing Eugenia plants. This is a problem that I have seen at many homes in Broward and Palm Beach Counties. The scales produce a lot of honeydew that ants feed on. Sooty mold also grows on this honeydew (black material on the leaves in the photo). My suggestion is to plant resistant ornamental varieties.

Name correction! This ant is Technomyrmex difficilis (click here)
Barry Bolton has determined the ant that we have here in Florida which we have been calling “white-footed ant” (Technomyrmex albipes), is really Technomyrmex difficilis (Bolton 2007). In Bolton’s description of difficilis he states: “Closely related to albipes but separated by the presence of setae [erect hairs] on the dorsum of the head behind the posterior margin of the eye (never developed in albipes) and by having the promesonotum somewhat longer and more slender… This species has been confused many times with albipes…”
James Wetterer at FAU is preparing an article regarding this name correction and plans to propose a common name for T. difficilis. I am not in favor of a different common name. I think that the common name for T. difficilis should be “white-footed ant” because that is how it is known in numerous publications and by the public in this country and a new common name will cause unnecessary confusion.
