Found 2 of these
1. Location of collection: East Ipswich on someones driveway
2. Date of collection: 18-10-2016
3. Habitat of collection: A driveway
4. Length (from head to gaster): 7-8 mm
5. Color, hue, pattern and texture: Very dark brown with shiny texture
6. Distinguishing characteristics: Long petiole node (longer than the ant queens I have collected so far)
7. Distinguishing behavior: They seem to be quite placid. The first one walked onto my scoop as if it wanted to be caught. The other one has a dried leaf in with it and seems to be residing on that leaf cleaning herself. They both occasionally curl up cleaning the tip of their gasters.
8. Nest description: Unknown. These queens were alone.
Notes: I am particularly interested to know if these are solenopsis invicta as they will need to be reported and surrendered to DAF QLD. The images aren't the best, but hopefully good enough for a +ve ID.
