As an adult I admit I am still a bit fascinated by them and I look for them each time I visit a bog. I hadn\u2019t really tried to learn anything about Sundews or Pitcher Plants, though, until I decided to share a few photos from our last trip to Peggy\u2019s Cove. Some simple research around the internet taught me a few new facts about the secrets of Sundews that I thought I\u2019d share.<\/p>\n<p><a href=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewLeafBonNaturalCrooksDotCom.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-2476\" alt=\"Photo of Spoon Leaf Sundew Leaf B on NaturalCrooksDotCom\" src=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewLeafBonNaturalCrooksDotCom-400x301.jpg\" width=\"400\" height=\"301\" srcset=\"https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewLeafBonNaturalCrooksDotCom-400x301.jpg 400w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewLeafBonNaturalCrooksDotCom-200x150.jpg 200w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewLeafBonNaturalCrooksDotCom-397x300.jpg 397w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewLeafBonNaturalCrooksDotCom.jpg 850w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a><\/p>\n<h2>How Do Sundews Eat Insects?<\/h2>\n<p>Unlike my research into Pitcher Plants that turned up a complex food web lurking within the tubular leaves of the Northern Pitcher Plant, the Sundew seems much more straight forward.<\/p>\n<p>The many tiny \u201ctentacles\u201d Sundews grow on their insect-eating leaves are very obvious when you glance at the plants. These plants then secrete a sticky sap that forms tiny beads along and at the tip of each red thread.<\/p>\n<p>Insects who brush against the sap can get stuck. If in their struggles they brush against more tendrils they get more firmly trapped. To make matters worse, for the insect, the \u201ctentacles\u201d can actually move. They slowly fold in around the disturbance, gradually enclosing it.<\/p>\n<p><a href=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewClosedPeggysCoveonNaturalCrooksDotCom.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2475\" alt=\"Photo of Spoon Leaf Sundew Closed Peggys Cove on NaturalCrooksDotCom\" src=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewClosedPeggysCoveonNaturalCrooksDotCom.jpg\" width=\"350\" height=\"337\" srcset=\"https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewClosedPeggysCoveonNaturalCrooksDotCom.jpg 350w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewClosedPeggysCoveonNaturalCrooksDotCom-200x192.jpg 200w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/SpoonLeafSundewClosedPeggysCoveonNaturalCrooksDotCom-311x300.jpg 311w\" sizes=\"auto, (max-width: 350px) 100vw, 350px\" \/><\/a><\/p>\n<p><em>To the back you can see a closed leaf. I believe the pod at the front is a seed pod.<\/em><\/p>\n<p>Once trapped against the leaf, the insect is \u201cdigested\u201d by enzymes secreted by the leaves. When the plant decides it\u2019s \u201cdone\u201d it unfolds. The dried exoskeleton of the insect eventually drops off or blows away.<\/p>\n<p>According to the <a href=\"http:\/\/eol.org\/pages\/593301\/overview\" target=\"strong\" rel=\"noopener noreferrer\"><strong>Encyclopedia of Life<\/strong><\/a> the sap itself is attractive to insects because it has sugar in it. The red colour of the \u201ctentacles\u201d may also attract some interest.<\/p>\n<p>Commonly caught insects include flies, mosquitoes, gnats and some small butterflies and moths.<\/p>\n<h2>Who Exactly Do Sundews Catch Insects For: Themselves or Others?<\/h2>\n<p>Well, it\u2019s not totally straight forward. <a href=\"http:\/\/link.springer.com\/article\/10.1007\/BF00377090\" target=\"strong\" rel=\"noopener noreferrer\"><strong>A study by Martin Thum<\/strong><\/a> says that ants often steal and eat insects caught by the Sundews. His work shows that up to two thirds of the prey caught by Round Leaf Sundews are taken by ants. It\u2019s not clear to me whether the ants provide any benefit to the plants.<\/p>\n<p><a href=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/RoundLeafSundewPeggysCoveonNaturalCrooksDotCom.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-2438\" alt=\"Photo of Round Leaf Sundew Peggys Cove on NaturalCrooksDotCom\" src=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/RoundLeafSundewPeggysCoveonNaturalCrooksDotCom-400x330.jpg\" width=\"400\" height=\"330\" srcset=\"https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/RoundLeafSundewPeggysCoveonNaturalCrooksDotCom-400x330.jpg 400w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/RoundLeafSundewPeggysCoveonNaturalCrooksDotCom-200x165.jpg 200w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/RoundLeafSundewPeggysCoveonNaturalCrooksDotCom-362x300.jpg 362w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2014\/02\/RoundLeafSundewPeggysCoveonNaturalCrooksDotCom.jpg 850w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a><\/p>\n<h2>Where Do Round Leaf Sundews Live?<\/h2>\n<p>According to various sources, Round Leaf Sundews are actually round the world Sundews.
