Myrmecia desertorum

Heterick (2009) - These ants are visual predators. Typical encounters with even a solitary forager shows that they are a formidable and aggressive species. Nest workers are also always ready to rush out of their mound to attack an intruder. Myrmecia desertorum is possibly the most common bulldog ant in the SWBP. Their nest mounds may be huge, up to 2 m in diameter (Ogata and Taylor 1991).

Identification
Myrmecia desertorum, Myrmecia fuscipes, Myrmecia gratiosa, Myrmecia nigriceps and Myrmecia vindex are all large to very large, reddish ants with red, brown or black heads and a black gaster.

Distribution based on Regional Taxon Lists
Australasian Region: Australia.

Biology
Workers forage during the day, making them an obvious component of the Australian Arid Zone. As with all species of Myrmecia, these are highly visual and aggressive ants, detecting intruders and threats from some distance away, turning towards them and either attaching or retreating, depending primarily on the proximity to the nest (the closer the nest the more aggressive these ants are).
