She takes a lot of Hail Mary shots, and this is the best she\u2019s done (so far).<\/p>\n<p>Like their smaller cousins (Beaverpond, Spiny, and Common Baskettails), Prince Baskettails are in the Emerald family Corduliidae and the genus Epitheca (from the Greek \u201cepi \u201cabove, upon\u201d and theca \u201cpouch, basket, receptacle.\u201d) Unlike other odonates, which oviposit by inserting an egg into a slit they cut in vegetation or by tapping the water with their abdomen to release the eggs within, baskettails large and small fly around with a clump of eggs at the tip of their abdomen. These they drop into the water, either all at once, or by flying inches above the surface, dragging and snagging the egg mass on aquatic vegetation. The glob of eggs reacts like those kids\u2019 toys that instruct \u201cJust add water;\u201d the strand swells and uncoils, and it may reach 20\u201d long and enclose as many as 1,000 eggs.<\/p>\n<p>While the other baskettails measure about 2\u201d or less, the Prince Baskettail (Epitheca princeps) is 2 \u00bc\u201d to 3 \u00bc\u201d long (darner-sized) &#8211; the largest baskettail and the largest member of its family. It\u2019s slim-bodied, with three dark spots on each wing (some, especially in the South, are <a href=\"https:\/\/bugguide.net\/node\/view\/1078959\/bgimage\">larger <i class=\"fa fa-external-link\"><\/i><\/a> and <a href=\"https:\/\/bugguide.net\/node\/view\/1351143\/bgimage\">spottier. <i class=\"fa fa-external-link\"><\/i><\/a>) Mature males have the <a href=\"https:\/\/bugguide.net\/node\/view\/398259\/bgimage\">bright green eyes <i class=\"fa fa-external-link\"><\/i><\/a> that are characteristic of their family. The only dragonfly you might confuse it with is the female Twelve-spotted Skimmer, which is shorter and has a heavier body and a <a href=\"https:\/\/bugguide.net\/node\/view\/1959162\/bgimage\">pale line <i class=\"fa fa-external-link\"><\/i><\/a> running along each side of its abdomen.<\/p>\n<p>Adults prey on small, flying insects, often hunting for mayflies high above the trees, and they may form feeding swarms at the end of the day. Though they are large and feisty, they are not quite at the top of the food chain \u2013 <a href=\"https:\/\/www.uwgb.edu\/biodiversity\/econotes\/2007\/dragonhunter.htm\">here\u2019s <i class=\"fa fa-external-link\"><\/i><\/a> a Dragonhunter with a Prince Baskettail. The <a href=\"https:\/\/bugguide.net\/node\/view\/935963\/bgimage\">large and spiny naiads <i class=\"fa fa-external-link\"><\/i><\/a> (immatures) nab underwater critters with their extendable mouthparts.<\/p>\n<p>Male Prince Baskettails patrol a large territory, as do some females when they\u2019re looking for a place to oviposit. Naiads hatch in a few weeks, using a hard bump on their heads to break out of the egg. They may live in the water for a year or two before emerging, spending their final winter as naiads in deep water where temperatures are more constant. The half-hour that it takes for them to emerge from the water, pull out of their exoskeleton, and lengthen and harden their wings for flight is a dangerous one, and one source said that only 1% of the naiads achieve adulthood.<\/p>\n<p>Here\u2019s <a href=\"https:\/\/bugguide.net\/node\/view\/457838\/bgimage\">a series of pictures <i class=\"fa fa-external-link\"><\/i><\/a> of a Prince Baskettail emerging &#8211; and <a href=\"https:\/\/bugguide.net\/node\/view\/1442425\/bgimage\">a picture <i class=\"fa fa-external-link\"><\/i><\/a> of the exuvia (shed skin).<\/p>\n<p>They rarely perch, and when they do, they hang vertically from a twig, and they often <a href=\"https:\/\/bugguide.net\/node\/view\/1675349\/bgimage\">curve their abdomen. <i class=\"fa fa-external-link\"><\/i><\/a> The BugLady has never seen a perched Prince Baskettail (unless, of course, she glanced at one and dismissed it as a Twelve-spotted Skimmer), but she read that they are more likely to be perched on cloudy days.<\/p>\n<p>On another topic completely, the BugLady is offering this without comment.
