Ravenel’s Stinkhorn, not Ravel’s!

Butterfly I.D. Correction

Painted vs. American LadyYesterday’s post about the Painted Lady butterfly has a mis-identified inset photo. Two butterflies in the genus Vanessa resemble each other closely – V. cardui (Painted Lady) and V. virginiensis (American Lady), both of which are found in the Northeast. While the main photo was correctly identified as a Painted Lady, the inset photo is an American Lady. Details enabling you to determine which of these migrating butterflies you are seeing can be found at http://bugguide.net/node/view/236368 . (Bugguide.net is an excellent resource for anyone wanting the identity of an insect or spider. You simply submit your photo and generous entomologists provide i.d.s). Many thanks to naturalist/author Kathie Fiveash for bringing this mis-identification to my attention.


Ravel’s Stinkhorn Fruiting

If anyone reading this blog considers fungi too boring to be of interest, they may be about to experience a change of heart. A group of fungi known as “stinkhorns” generate a lot of interest, mostly because of their appearance and their odor. These fungi vary in color, shape and size, but they all share two characteristics. All stinkhorns begin fruiting by sprouting an “egg” from which they erupt, often as quickly as overnight, and a portion of their fruiting body is covered with slime (gleba) which contains spores.

Many species of Stinkhorns have a phallic form, including Ravel’s Stinkhorn (Phallus ravenelii). Brown, foul-smelling, spore-laden slime is located at the tip of this fungus. Attracted by the odor, insects (mostly flies) land and feed on the slime. With bellies full and feet covered with spores, the flies depart, serving as efficient spore dispersers.
