Green treefrogs are calling! These small frogs are green with a white stripe running down the sides. Some have gold specks on their back. This species lays eggs June-July, and calls May through August. They live near permanent bodies of water, preferring swamps and river sloughs with vegetation. Their call is a repeated nasally “quank quank quank”. In Missouri, they occur primarily in the bootheel.

Jelly fungus are rubbery mushrooms that grow on logs, stumps, and twigs. They shrink when the air is dry and swell when it rains. Jelly fungus such as this wood-ear grow in clusters. They are cup shaped and irregularly lobed, resembling ears. As they dry, they will turn black. They can be found on dead trees and logs along the boardwalk trail.

Have you ever seen a prothonotary warbler? These vibrant yellow and blue-gray birds are warm weather residents at Big Oak Tree. Walk down any of our trails, and you will be sure to hear them singing in the trees. The song is a loud “tsweet-tsweet-tsweet-tsweet-tsweet”. You may even catch a glimpse of one as they flit about looking for food. They prefer habitats near water, and they nest in tree cavities. These warblers arrive in Missouri in April and begin their migration south in August.

This young western ratsnake (or black rat snake) was hanging out in the park this weekend. Black snakes are non-venomous and harmless to humans. They are common in Missouri, and can reach more than 72 inches in length. They are constrictors, and primarily eat rodents. When hatched, the young are grey with black splotches, and darken to solid black as they age.

Five lined skinks are common lizards that inhabit Big Oak Tree. As juveniles, they are black and yellow striped with blue tails. As they mature, they lose their colorful stripes and become brown with darker stripes down the side. Females retain some blue in their tails, and males develop orange color under their chins during mating season. Eggs are laid April-June in leaf litter or rotten logs, and females guard the eggs until they hatch. Look for them along the boardwalk trail, where they find plenty of insects and spiders to fill their bellies.

What’s that blooming in the borrow pit? The sea of yellow blooms are ragworts, which belong to the Asteraceae family. We have seven different species recorded in Missouri. The small yellow flowers look similar to a daisy and bloom April-June. This species occurs in floodplains and tributaries. Ragworts are poisonous if eaten, but the flowers provide nectar and pollen for a variety of insects.

This brightly colored snake was spotted near the boardwalk trail. It is an orange-striped ribbonsnake. This member of the non-venomous garter snake family is usually found near water. They have an orange stripe along the middle of the back, and yellow stripes on the sides. They typically eat frogs, toads, salamanders, and earthworms. They have a prominent spot on the head, which can help distinguish them from other garter snakes.
Fun fact: The ribbon snake has a very long tail, up to 1/3 of it’s body length!

Wild petunia is blooming in the woods this week at Big Oak Tree! Native to Missouri, this plant is a shy bloomer, and flowers only last for one day. It grows in open woods, stream sides, and moist uplands. While it is botanically not related, the flowers do resemble garden petunias. This weekend is a great time to visit at Big Oak tree, as the biting bugs are not bad right now! Also blooming this week is green dragon, which we talked about in a previous post.

Have you ever been lucky enough to see a luna moth? These beautiful large moths appear April-August in Missouri. They belong to the giant silk moth family (Saturniidae). After mating, the females lay about 200 eggs, which hatch about 10 days later. The caterpillars eat walnut, hickory, persimmon, and sweet gum leaves. They form a cocoon from silk and leaves, and after about 3 weeks the moth emerges. The adult moths do not eat and only live for about a week.

Fun facts: Luna moth caterpillars make clicking sounds and can vomit to keep predators away!
The long tails on the adult moths are thought to disrupt the echolocation that bats use to hunt!
