So a few days ago, the first out of two Nylanderia cf. vividula queens I have had workers eclose. Out of all my colonies, this was by far the single species that had the largest amount of brood in her first clutch a total of about 12 workers eclosed all together, with more pupae following soon. I see why this species drove even the famously invasive Linepithema humile out of Simi Valley. Another thing, they run FAST. The queen alone runs faster than any of my other ant species' workers. The workers almost fly through the test tube, which makes feeding a little difficult, but once the fruit fly is in, it is quite interesting to watch.
It is funny, when they are callow workers and start getting darker, their head and thorax become almost completely black, but their gaster still looks completely unpigmented, making them look like Tapinoma melanocephalum, but later, their gaster becomes dark too.
