Early eastern tent caterpillar egg hatch anticipated for Central Kentucky

by Holly Weimers, University of Kentucky

It is likely eastern tent caterpillars will begin to hatch soon, according to Lee Townsend, University of Kentucky College of Agriculture, Food and Environment extension entomologist.

“Eastern tent caterpillars are among the first insects to appear in the spring. Consequently, they can cope with the erratic temperature swings that are common in Kentucky. This year’s unseasonable warmth points to abnormally early activity,” Townsend said. Continue reading

Instead it aggregates between feedings on a silken mat which is spun on some area of the trunk or on large branches of the host tree.

In spring 2012, a cankerworm outbreak occurred in many North Carolina cities.  Hundreds of silk threads blocked sidewalks on campus.  Students became tangled in threads and covered in caterpillars as they walked to class.  I got a lot of calls and emails from landscapers and arborists wondering why there were so many caterpillars.  “Are these cankerworms?” they would ask. “Will my trees die? What can I do?”  I will answer some of these questions in this article.  Others will have to wait until our research is done this year.
