Day 234. Elm beetle

My father-in-law is in a state of panic.

The leaves of his magnificent Golden Elm tree look like they’ve been shot with a small pellet gun.

Fortunately, our family gardening guru has nailed down the culprit to be the Elm Leaf Beetle, or Xanthogaleruca luteola.

The beetles are a native of Europe, and migrated across the world to reach Eastern Australia during the 1980s and 1990s. The wee blighters cause damage to elm foliage in two ways: the shotgun pellet-like holes result from adults having a chew, whereas the larvae leave a partially skeletonised leaf behind them. In severe cases, defoliation can lead to death of the tree.

Fortunately, professional tree servicers suggest

“one or two years of Elm Beetle damage or ongoing moderate damage is very unlikely to kill the host tree, unless there are other significant contributing factors.”

Settle down Pa.
