Pogonomyrmex anzensis
● Anza-Borrego Desert S.P., Ocotillo Wells Vehicular Rec. Area, [San Diego Co], CA USA [el. 121 m / 398 ft] map location not yet available » ● 4/06/11 12:41PM overcast, breezy, air temp: 30°C / 86°F
[Image 2 of 2] As mentioned earlier, these ants Pogonomyrmex anzensis did not stand still, or congregate around the nest entrance - making them very difficult 'moving targets' for imaging. Thankfully, a couple of workers paused for a few moments to engage in some self-grooming behavior. The forelegs were drawn along the length of the antennae, and also inserted between the ants' mandibles. Not visible in these images are the tiny pectinate (comb-like) tibial spurs on the ants' forelegs. These structures, combined with grooves on the legs themselves form the tibio-tarsal antenna cleaners, through which the antennae are drawn. [scroll down for additional notes/references]
ADDITIONAL NOTES/REFERENCES:
These grooming actions not only remove fungus and other debris, but may also serve to spread antibiotic secretions over the ant's body. In many ant lineages, much of this bacteria-fighting substance is secreted from the metapleural gland, located on the ant's mesosoma, the 'middle' body part (also called the alitrunk). There is also evidence that some ants posses a gland that is incorporated in the 'antenna cleaner' (strigilis) itself. It is unclear if the secretions from this gland aid solely in the cleaning of the antenna, or serve as a means of chemical communication - perhaps they fulfill both of these roles. As mentioned elsewhere on this site, grooming (and self-grooming) behaviors also distribute the chemical compounds ('cuticular hydrocarbons') that allow ants to discriminate between nestmates and intruders, regulate worker tasks, and also permit identification of reproductive status between colony members.

on December 2, 2014Hello
I'm assisting the Museum of Northern Arizona's education team in finding images for a flyer that announces a lecture series about venomous invertebrates, reptiles and plants.
We found this superb ant photo below at http://bugguide.net/node/view/723022 I then went to pogolumina.net for your e-address where this photo also is located.
MNA is a non-profit organization, EIN 86-0098920. For non-profit educational use would it be possible to obtain permission to print this photo of yours on a color flyer, providing we did not alter it in any way?
Could you send a high resolution copy in that case, or high resolution of a similar photo (such as the one featured on your home page), and would there be a charge?
And if selected by the designer from a choices we've given her, would this be a correct photo credit?

And possibly if there is room, also this as part of the caption: Pogonomyrmex anzensis (a harvester ant species)
It's for a flyer that is needed tomorrow, Dec. 3 - yikes, and sorry for the extremely short notice!
I'm copying graphic designer Mary Ross, MNA Marketing Manager Cristen Crujido , and MNA curator of biology/ecology Dr. Larry Stevens on this e-mail.
