Its Time for Cultural Management of Fall Cankerworm

Homeowners and horticulturalists alike will remember being inundated with tiny, green loopers feeding voraciously on many of our shade trees this past spring (Acer, Betula, Celtis, Fagus, Malus, Quercus, Tilia, Ulmus).  These were the larvae or caterpillar stage of the Fall Cankerworm (Alsophila pometaria).

Larvae are light green with thin longitudinal white stripes down their bodies and 3 pairs of prolegs at the end of their abodomen (although, the first pair is much smaller and you might miss seeing it).  Larvae grow to 2.5 cm long. There is also a black-green race.  (Photo: Dave Cheung).  Continue reading

Today marks the first day of Autumn.  And with it another interesting calendar event, the Autumn Equinox.  Like the Spring Equinox (March 21), the Autumn Equinox marks a unique period of time where the length of daylight and night time hours are pretty much equal.  So as you can imagine, the wildlife can get a little confused this time of year.  If you spend time outdoors you might notice the odd mating song of birds and frogs.  I have heard a lot of male Grey Tree Frogs singing in the last week or so.  How cool is that?  Continue reading
