Eastern tent caterpillars are active in early summer, while fall webworms feed in late summer. These caterpillars will become moths in their adult phase. The forest tent caterpillar is another type of \u201ctent caterpillar\u201d in Ontario, but it does not produce large, noticeable tents in the forks of trees like the eastern tent caterpillar.<\/p>\n\n\n\n<p>Tent caterpillars make their cocoons in midsummer, while fall webworm cocoons are formed in the fall. Right now, residents may be seeing the newly opened cocoons of eastern tent caterpillars, which are now in their adult phase. Cocoons of fall webworms will become more noticeable as fall progresses.<\/p>\n\n\n\n<p>Populations of these caterpillars are cyclical, increasing and decreasing over time. Tent caterpillar outbreaks occur about every ten years and sometimes last up to two years. The fall webworm population is typically high for two or three years before returning to lower levels. Caterpillar outbreaks often end due to increased predation and disease.<\/p>\n\n\n\n<p>Outbreaks of fall webworm typically have little effect on tree health because the damage occurs at the end of the growing season. Tent caterpillars seldom kill infested trees, but they can reduce a tree&#8217;s health since they feed earlier in the growing season. Healthy trees can handle minor damage. However, according to the Ministry, repeated defoliation can weaken trees, making them more susceptible to other forms of stress.<\/p>\n\n\n<h5 style=\"text-align: center;\">Don\u2019t miss out on Doppler!<\/h5>\n<p style=\"text-align: center;\"><strong>Sign up <a href=\"https:\/\/doppleronline.ca\/huntsville\/dont-miss-out-on-doppler\/\"><u>here<\/u><\/a> to receive our email digest with links to our most recent stories.<br \/>\nLocal news in your inbox so you don&#8217;t miss anything!<\/strong><\/p>\n<p style=\"text-align: center;\"><a style=\"background: #5cb85c url('https:\/\/d1iczxrky3cnb2.cloudfront.net\/red_logo.png') no-repeat 37px; color: #fff; text-decoration: none; font-family: Verdana,sans-serif; display: inline-block; font-size: 16px; padding: 15px 38px; padding-left: 75px; -webkit-border-radius: 2px; -moz-border-radius: 2px; border-radius: 2px; box-shadow: 0 1px 0 0 #1f5a89; text-shadow: 0 1px rgba(0, 0, 0, 0.3);\" href=\"https:\/\/donorbox.org\/support-huntsville-doppler\">Click here to support local news<\/a><\/p>\n<p style=\"text-align: center;\"><broadstreet-zone zone-id=\"45657\" keywords=\"\" soft-keywords=\"true\" zone-alias=\"\"><\/broadstreet-zone>\n","protected":false},"excerpt":{"rendered":"<p>You&#8217;ve probably noticed these creepy cocoons in the trees, which seem rather prolific, particularly this time of year.
