T. gigantea is the largest giant ant ever found, larger than the biggest extant giant ants, which are the five-centimetre-long (2.0 in) driver ants of the genus Dorylus, found in Central and East Africa. [1] [6] The fossils indicate that the males grew up to 3 centimetres (1.2 in) and the queens grew to 7 centimetres (2.8 in). It had a wingspan ...
An additional cause that may be specific to insects is light pollution (research in that area is ongoing). [7] [8] [9] Most commonly, the declines involve reductions in abundance, though in some cases entire species are going extinct. The declines are far from uniform.
The most frequently cited example is that of the extinct passenger pigeon and its parasitic bird lice Columbicola extinctus and Campanulotes defectus.Recently, C. extinctus was rediscovered on the band-tailed pigeon, [4] and C. defectus was found to be a likely case of misidentification of the existing Campanulotes flavus.

Gracilidris is a genus of dolichoderine ants with nocturnal behaviour; thought to have gone extinct 15-20 million years ago, they have been found in Paraguay, Brazil, and Argentina and were described in 2006.
Sphecomyrma is an extinct genus of ants which existed in the Cretaceous approximately 79 to 92 million years ago. The first specimens were collected in 1966, found embedded in amber which had been exposed in the cliffs of Cliffwood, New Jersey, by Edmund Frey and his wife.
A 2017 analysis found that the mountain goat populations of coastal Alaska would go extinct sometime between 2015 and 2085 in half of the considered scenarios of climate change. [102] Another analysis found that the Miombo Woodlands of South Africa are predicted to lose about 80% of their mammal species if the warming reached 4.5 °C (8.1 °F). [1]
The notorious ant genus Myrmecia is known for their venomous stings and aggression, which has caused several human deaths in sensitive people. Subfamily Myrmeciinae Emery, 1877 – seven genera, 111 species [ 182 ]
