Hemlock Woolly Adelgid and Online Workshops

Hemlock woolly adelgid (HWA) discovered in Ontario

The hemlock woolly adelgid has been found in Fort Erie. If you are in this area, do not move hemlock or any type of firewood to prevent further spread.

What is HWA?

HHWA is similar to aphids in that they suck fluid from their hosts. They feed on cells storing nutrients and water at the base of hemlock needles, causing the needles to die. There are two forms of the insect, each of which lay up to 300 eggs each year. This can result in exponential population growth due to the absence of natural enemies.

You Are Ontario’s Early Warning System: Spotted Lanternfly NYMPHS!

Spotted lanternfly nymphs (top row) and adults (bottom row).

Here’s a pest you have been hearing about more and more, the Spotted Lanternfly (Lycorma delicatula).  It is not a fly, but a planthopper. In the Order Hemiptera, Family Fulgoridae.  It is actually a much stronger hopper than it is a flyer.  They may remind you of frogs they way they sit and hop around. Found recently in the US and now spreading rapidly across several states,  Spotted Lanternfly is a pest we are actively looking for in Ontario.
