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.
Top: An ant in Mozambique Bottom: An ant-mimicking spider, Myrmarachne Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive.
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 ...
The colonies of M. nigrocincta ants are monogyne, i.e. they have only one queen per colony. [4] The queen is semi-claustral, meaning that during the founding of the new colony, the queen has to forage so that she has enough food to raise her brood. [4] [18] Colonies have between 400 and 1200 individuals and are thus considered to be "large ...
Spiders do not have compound eyes, but instead have several pairs of simple eyes with each pair adapted for a specific task or tasks. The principal and secondary eyes in spiders are arranged in four, or occasionally fewer, pairs. Only the principal eyes have moveable retinas. The secondary eyes have a reflector at the back of the eyes.
Leafcutter ants have very specific roles in taking care of the fungal garden and dumping the refuse. Waste management is a key role for each colony's longevity. The necrotrophic parasitic fungus Escovopsis threatens the ants' food source and thus is a constant danger to the ants. The waste transporters and waste-heap workers are the older, more ...
From June 2009 to December 2012, if you bought shares in companies when Alfred F. Kelly, Jr. joined the board, and sold them when he left, you would have a 12.1 percent return on your investment, compared to a 59.3 percent return from the S&P 500.
