Compared to vertebrates, ants tend to have blurrier eyesight, particularly in smaller species, [44] and a few subterranean taxa are completely blind. [12] However, some ants, such as Australia's bulldog ant, have excellent vision and are capable of discriminating the distance and size of objects moving nearly a meter away. [45]
These ants have excellent vision, having the largest eye lenses and photoreceptors than any other Myrmecia ant. [20] These ants are capable of discriminating the distance and size of objects moving nearly a metre away, sensitive to motion and will rapidly charge towards any moving objects to attack it. [24]
Closeup view of a bull ant eye. While most ants have poor eyesight, Myrmecia ants have excellent vision. [70] This trait is important to them, since Myrmecia primarily relies on visual cues for navigation. [217] These ants are capable of discriminating the distance and size of objects moving nearly a metre away. [218]
The two pests also have a difference in behavior: According to Yates-Astro Termite and Pest Control in Georgia: “Flying ants are attracted to light and are often seen flying around lights at ...
The compound eye and the ocelli supply insect vision. The compound eye consists of individual light receptive units called ommatidia. Some ants may have only one or two, however dragonflies may have over 10,000. The more ommatidia the greater the visual acuity. These units have a clear lens system and light sensitive retina cells. By day, the ...
Ants want to shelter from the pounding raindrops, but their underground colonies can get flooded. They also can be swept away in the downpour, since ants, like most insects, can float.
They rely on their vision to navigate and there is no evidence to suggest that the species use chemicals to communicate when foraging, but they do use chemical alarm signals. A queen ant will mate with one or more males and, during colony foundation, she will hunt for food until the brood have fully developed.
Truthfully, it was a blessing in disguise that these biting, wood-loving ants fell on Andrew and his wife that night: Had they not been there, the colony could've easily done a lot of damage to ...
