Landscape Message: May 20, 2016

Selection from Report by Tawny Simisky, Extension Entomologist, UMass Extension Landscape, Nursery, & Urban Forestry Program:

"Cater-PALOOZA: A suite of caterpillars has been out for a while
now, but are really picking up their pace as host plant foliage has
expanded and we’ve experienced some warm weather and degree day
accumulation. Multiple species can be found on shared hosts, such as
these gypsy moth and winter moth caterpillars found on the same oak.
Eastern tent caterpillar has been feeding now for some time and the
cankerworms and forest tent caterpillar have joined us. Gypsy moth
numbers are up this season and caterpillars are seen feeding on oak and
other hosts. They are ballooning onto other hosts as competition rises
and some folks have experienced dermatitis due to the insect’s
urticating (irritating) hairs (see notes below). The Elkinton Lab has
found 4th instar winter moth in Seekonk and Wellesley, but 2nd and 3rd
instars are still out there."

Claire, I remember from many years ago that UMASS Extension used to include a variety of weekly updates, like lawn, shrubs, etc, and notes you provided in your post. Does this news posting still exist? Is that a subscription item?? I have a friend on the Cape that is going nuts with the catepillars, and various other planting issues. Can you help me? You can email me privately if you wish: crnaskater@yahoo.com Thanks for any help!

crnaskater: UMass Extension used to publish Hort Notes and Garden Clippings printed newsletters. I think the paper versions have been discontinued but the information is still available online at this site, and there are links where you can ask a specific question:
Home Lawn & Gardens

These are screen shots so the links don't work here - use the links I provided to go to the site.
