Agrilus anxius, the bronze birch borer, is a wood-boring buprestid beetle native to North America, more numerous in the warmer parts of the continent and rare in the north. [1] It is a serious pest on birch trees (Betula), frequently killing them. The river birch Betula nigra is the most resistant species, while other American birches are less so.
Agrilus is a genus of jewel beetles, notable for having the largest number of species (about 3000) of any single genus in the animal kingdom. [3] Species of the genus have a cosmopolitan distribution on all continents except Antarctica, [ 4 ] and feed on a wide variety of flowering plant hosts. [ 5 ]
Anhingas or darters are often called "snake-birds" because of their long thin neck, which gives a snake-like appearance when they swim with their bodies submerged. The males have black and dark-brown plumage, an erectile crest on the nape and a larger bill than the female. The females have much paler plumage especially on the neck and underparts.
Like other North American birches, gray birch is highly resistant to the bronze birch borer (Agrilus anxius). [10] This is due to birches in North America sharing a coevolutionary relationship with the borer, allowing it to develop resistance to the bug. Despite this, the borers can still damage the trees if they are weakened by other means.
Birch dieback is a disease of birch trees that causes the branches in the crown to die off. The disease may eventually kill the tree. In an event in the Eastern United States and Canada in the 1930s and 1940s, no causal agent was found, but the wood-boring beetle, the bronze birch borer, was implicated in the severe damage and death of the tree that often followed.
It has unique patterning on its body, which is not easily confused with other southern African snakes. Spotted house snakes are small and slender, with the average length of 40–60 cm (16–24 in), and a maximum length of 65 cm (26 in). The body is cream white to light brown, with round spots, which are dark brown.
