Sonoran desert cacti are frequently covered in ants. Cacti provide ants with nectar- a ready food supply in a harsh environment- in exchange for protection from herbivorous insects. Here, two Crematogaster opuntiae acrobat ants exchange nectar they have gathered from a chain-link cholla. Tucson, Arizona, USA - Alex Wild Photography - Insect Photography

is an abundant, ecologically diverse myrmicine genus found worldwide. These ants- sometimes called "Acrobat Ants"- are easily recognized by their unusual heart-shaped gasters.

Several genera of myrmicine ants, including Crematogaster, attach intermediate-age larvae to the walls and ceiling of the brood chamber. These larvae have long, anchor-shaped hairs along their backs that hook into the substrate like velcro. (Crematogaster nigropilosa)

Crematogaster nigropilosa. Unlike most stinging insects, ants of this genus don't use their stingers to inject venom. Rather, Crematogaster employ theirs like a brush to smear a droplet of venom on their attackers. This worker exudes a droplet in response to the photographer.
