Subfamily Myrmeciinae - Bulldog Ants and Jumper Ants

This page contains pictures and information about Bulldog Ants and Jumper Ants that we found in the Brisbane area, Queensland, Australia.
The ants in subfamily Myrmeciinae are among the largest ants, often reach 15 mm, up to 45mm,  in body length. The Myrmeciinae are found almost exclusively in Australia. 
They are easily recognized by their large body size, large eyes and long forward mandibles. The workers possess ocelli and sting well developed. They are often in bright colours. Ants in this subfamily are considered to be the most primitive of all living ants. They have the relatively simple social structure. Their workers and queens are about the same size. 
They are fast and aggressive. They have good vision. They show a strong and well developed sting. They will not hesitate to deliver a painful stings to any intruder.

Ants in Myrmeciinae have the mesosoma attached to the gaster by two distinct segments, the petiole and postpetiole. The mandibles are very long and straight, with teeth along their inner margin. There is the sting at the tip of their gaster.
Workers forage on ground or on low vegetation during the day. A few species will also forage at night. They collect nectar as well as prey on insects. Most species nest in soil, a few in rotten logs. Their nest is usually domed shape on ground covered with plant materials. Their colony is small, usually up to a few workers.  
The subfamily contains a single living genus Myrmecia. 

Bull Ants in this group are large in size with long legs. 
Giant Red Bull Ant

Myrmecia gulosa, body length 25mm
We found the Giant Red Bull Ant nest entry when we were walking up to top of Mt Gravatt. It was next to the footpath. There were not much activity. Just inside the nest entry, there were a few guards standing by. When we came within a meter, they ran out and put up a attack posture. Fir more information and pictures please visit this page.
Giant Brown Bull Ant
 DSC_4540.jpg (138179 bytes)
Myrmecia pyriformis or M. brevinoda, body length 25mm
In Brisbane Forest Park, we found another species of Bulldog Ants. They are dark brown in colour. Their hind legs are not as strong as the species shown above, we did not see it jumping. We found this ant foraging alone on the ground. It was very aggressive. When we came close, it did not retreat but put a fighting posture, waving its head with its huge jaws. More information and pictures in this page.

The Bull Ants in this group are medium in size. They are characterized by the reduced teeth on mandibles. Their body colour is black but the legs may be different colours. 
Toothless Bull Ant
DSC_9528.jpg (203548 bytes) wpe3.jpg (45153 bytes)
Myrmecia fulviculis, or M. mandibularis, body length 15mm
The ant has the black head and body, red legs and golden abdomen. Notice its jaws are relatively smooth comparing with other bull ants, i.e., its common name Toothless Bull Ant. More information and pictures can be found in this page.

Bull Ants in this group is small to medium in size. They have very long legs
Jumper Ant

Myrmecia nigrocincta, body length 15mm
We found those Jumper Ants in Brisbane Toohey Forest. The workers foraging alone on low vegetation during the day. They are large in body size, with large eyes and elongated mandibles. They are bright colour, with dark green head and brown body and dark brown legs. More information in this page.
Giant Jumper Ants

Myrmecia sp., body length 25mm 
We occasionally found this large ant foraging alone on forest ground. They are dark blue and brown in colours. The colour patterns are exactly the same as the Jumper Ants above but double the body size. So we called them Giant Jumper Ants. We have more pictures and information in this page.
Toothed Bull Ant
DSC_4529.jpg (131970 bytes) PWC_9092.jpg (149069 bytes)
Myrmecia chrysogaster, body length 15mm
This medium size bull ant is found either on leaves or tree trunk. Usually we found a small group of them running up and down along tree trunk. Please check this page for more information. 

Ants in this group are small in size as Bull Ants. 
Baby Bull Ant 
wpe16.jpg (49011 bytes) wpe1C.jpg (64354 bytes)
Myrmecia urens, body length 12mm 
Baby Bull Ant is the smallest among the Bulldog Ants family. We found one resting on a gum tree trunk in Karawatha Forest in mid September. More information and pictures please find in this page.

We found this golden and black bull ant on Eugenia Circuit near Simpson Falls on Feb 2012.  

Jumper Ants Sting
DSC_6958.jpg (76376 bytes) Bulldo12.jpg (21210 bytes)
Our visitor Cheryl sent us email about her experience with Jumper Ants sting; 
"We put down a tarpaulin and picnic rug on medium length grass in a little visited spot (not a regular picnic area) on the northern edge of Mt Tamborine. The next thing I knew, I was being literally 'aggressively attacked' by a swarm of jumping ants, black and yellow in colour. I ran away, trying madly to shake the things off, and eventually ensconced myself back in the car where I continued to pluck them off one by one. 
"I was screaming with the most horrific pain, especially in the arch of my left foot which suffered multiple bites/stings. I continued to scream in agony for about 10 minutes. I went pale and cold and clammy; I felt nauseous, and my heart palpitated. 
"Fortunately we had some 'Soov' in the car, which I rubbed into the affected areas; and I applied ice from out of our esky. But even so, it took a couple of hours for the pain to dissipate."

Fire Ants - We are suffering the Fire Ants problem. 
The Red Imported Fire Ant, Solenopsis invicta, is a serious new pest which has been detected in Brisbane, Queensland. 
They can be the greatest ecological threat to Australia. More information please visit our Government Fire Ants web site.
