Fashion icon alert!

The tiger swallowtail butterfly gets its name from the stripes on its wings and the forked “tails” on its hindwings. The tails easily break off in the mouths of predators like birds, allowing this fashionable flier to flutter away.

Male tiger swallowtails are always yellow, but females can be yellow or black. Female tiger swallowtails also have blue marks on their hindwings. Can you tell which of these swallowtails is male?

If you want a chance to spot these butterflies and other New Jersey pollinators, come to Pyramid Mountain’s Butterfly Bonanza this Saturday on June 6th! The event runs from 12-4pm and is only $5/person ages 3 & up; 2 and under FREE. We hope to see you there!

When people think about mushrooms, they usually imagine a toadstool, a mushroom with a stalk, a round cap, and gills underneath. Like the highly poisonous blusher amanita mushroom (Figure 1).

But mushrooms come in a variety of different shapes!

(Figure 2) Shelf fungi, like this turkey tail, have no stalks. They grow right out of the side of trees and rotting logs!

(Figure 3) Some mushrooms, like this coral fungus, have no caps at all! Instead they have multiple branching stalks like some species of coral.

(Figure 4) Strangest of all are the jelly fungi like this witch’s butter. On dry days they are shriveled brown bits stuck to tree branches, but when it rains, they swell up and become gooey like Jell-o.

Come for a walk at Pyramid Mountain or the Great Swamp OEC on a rainy day and check out our local fabulous fungal forms!

As the weather warms up New Jersey’s snakes come out to play, let’s take a look at a few of the common snakes of Morris County!

(Figure 1) First up is the eastern garter snake.
The garter snake is the most commonly sighted snake in New Jersey and can be identified by the yellow stripes along its body. Contrary to popular belief, garter snakes are slightly venomous! The venom is not dangerous to humans, they use their venom to help hunt their prey, which is mostly worms and amphibians.

(Figure 2) Next is New Jersey’s biggest snake, the eastern rat snake.
Named after its habit of hunting rats, the rat snake can reach lengths exceeding 7 ft! It is non-venomous.

(Figure 3) The most common dangerous snake in Morris County is the eastern copperhead.
Copperheads can be identified by the hourglass-shaped markings on their backs. They aren’t aggressive and their bites are rarely fatal, but they should be left alone regardless.

If you hike at Pyramid Mountain or the Great Swamp on a sunny day, keep your eyes peeled for some snazzy snakes!

Last Saturday’s World Series of Birding was a success despite the rain! We saw or heard a total of 64 species throughout the 4 parks we visited. Pictured here is an Eastern Towhee that we saw at our first location, Johnathan’s Woods, and a Great Egret we spotted at the pond right here at the GSOEC. Thank you to the members of the public who braved the rain to join us on our birding adventures.

Recently staff at both Pyramid Mountain and the Great Swamp OEC spotted luna moths at the parks on the same day! These magical looking creatures are one of the biggest moths we have here in NJ. They only live about a week in their adult form and don't eat or drink that entire time.
