The colour of Platypus apicalis is mainly dark-brown, with yellow basal joint of antennae, metathorax and femora.

The body of females is more pubescent than this of males, lack elytral teeth, and have a more rounded shape.

[4] Adult males release a strong and distinguishable odor to attract a female upon digging a breeding gallery.

In contrast, fully grown larvae are white, cylindrical and legless with yellow coloured heads.

At this stage the mandibles begin to orient downward and ridges start to appear on the top of the prothorax.

Few fungi are related to pinhole borer closely, they benefit beetles in different ways.

[7] The beetle has no preference for hard or soft wood as it resides inside the Beech trees and some Eucalyptus species.

In addition, their tunnels, which go deep into the wood, create imperfections in the finished timber, which also weakens it.

[6] The life cycle begins with a male adult boring a tunnel into a host tree and releasing fungal spores along the way.

[9] However, not like the other bark beetles that they rely on the inner tunnel, adults and larvae both will soon acquire the primary food.

During the feeding stage, yeasts are likewise transmitted by bark beetles, but their precise role has not been discovered yet.

The pair will feed the larvae until they reach maturity using specialized structures called mycangia, which is located on the head of the adult.

[2] Finally, when two years have passed since the egg laying, adult beetles emerge from the chambers and exit the tree.

[10] The xylem and phloem tissue of the tree is merely a medium for the fungus, it is not a source of food for the beetle.

displayed that C. australis was not subject to P. subgranosus for transmission or for entry to the trees, despite the way that P. subgranosus are of critical in ailment spread through opportunity of polluted frass and the making of wounds in concentrated on trees [13] Platypus apicalis has both biodiversity and economic impacts.

While some trees have been known to survive, in most cases the combination of the tunnels through the xylem and phloem and the subsequent fungal infection prove lethal.

This and the fact that it has no known predators and few parasites makes it a potential threat to beech tree population numbers.

[2] Even if a tree is not killed outright, the invasion often causes defects such as concealed rot pockets and irregular wood cores.
