|At a Glance||• Supercolonies|
A member of the Tapinoma nigerrimum complex.
The introduced colony of Tapinoma ibericum at the Ventnor Botanical Garden, Isle of Wight, UK, is still going strong as of October, 2020. It was expected that it would die out during its first winter a couple of years ago, but workers are still running about all over the path in the bright sunshine (B. Bolton).

Seifert et al. (2017) - There is almost nothing known on the biology of this species except for the fact that it may form large supercolonies. Tapinoma ibericum apparently has a weaker tramp species potential than Tapinoma magnum. Only one anthropogenous introduction is known so far: A mature polydomous colony was found in the Ventnor Botanic Garden on the Isle of Wight in 2016 which was probably founded during the import of several large plants from southern Spain some ten years ago (C. Pope, pers. comm.). Apart from this finding, T. ibericum seems to be restricted to its native range in Iberia south of 41° N – an area probably not exceeding 250,000 km2. It is unknown if T. ibericum is abundant along the shore line of southern Iberia because there was no systematic sampling at coastal sites. The phenology of sexual production, as derived from our poor data, seems to be comparable to the situation in the other species: 15 May ± 28 d [24 April – 15 June] n = 5. Low foraging temperatures are apparently also typical for this species: according to observation of the senior author in Portugal 14 February 2016, it was the only ant species showing surface activity at air temperatures of 10 °C.
