Hi, we have an ant species running around in our flat in Kowloon, Hong Kong, very likely a Pheidole, and I was wondering whether it might be possible to further identify it based on these pictures I made:
I don't know much about ant morphology, so in case I should make a picture of some special anatomical trait, I'd do my best :)
I have taken a look at the pictures you linked. The ant in question is the common tropical house and garden ant Pheidole megacephala, a.k.a. big-headed ant. The large-headed wingless one is a major worker, the smaller one a minor worker, and the winged one on its back is a male.
Thanks for writing the AntBlog!
