Weekend Insects

While botanizing this past weekend, I ran into an array of interesting insects, including one yellow jacket that wasn't too happy to be stuck under my shirt sleeve. Below are some photos of the more docile and cooperative species that I saw.



This gorgeous fluorescent blue and black-striped damselfly is in the group called bluets. The best that I can tell, this is a Tule Bluet (Enallagma carunculata). As always, help with identification, if I'm wrong, is much appreciated. This individual was observed at Merry Lea Environmental Center, close to Bear Lake, in Noble County, Indiana. Take a gander at the look he is giving me in the photo below. I think he's had enough of me chasing him around.


At the pannes north of Miller Woods in Lake County, Indiana, I saw the female Eastern Amberwing (Perithemis tenera) pictured below. This small, orange-tinged dragonfly, which is typically less than an inch long, can be confused for a wasp because of its size and the way that it moves in flight. Males of this species don't have the spotted wing pattern that the females do, but instead have solid amber-colored wings. Eastern Amberwings are most often found over lakes and ponds.


Also in one of the pannes, I ran into this crazy creature...


Ever seen anything like it? I sure hadn't. This white and black-checkered member of the long-horned beetle family is a Cottonwood Borer (Plectrodera scalator). The pattern on this beetle reminds me of a Rorschach inkblot test. Cottonwood Borers have a body that is over an inch and a half long, with spiny antennae that alone exceed that length! As the name implies, this species relies on Eastern Cottonwood (Populus deltoides), willows (Salix spp.), and other members of the willow family (Salicaceae) for multiple stages of its life cycle. In the photos above and below, the adult Cottonwood Borer is feeding on Bayberry Willow (Salix myricoides).



Have a close look at those mandibles. It's amazing that they only eat leaves and young twigs! After mating, the female lays eggs in pits at the base of a Salicaceous tree. The larvae hatch and burrow further into the tree, feeding as they go. This process can take up to two years. The larva then pupates in a root below ground, metamorphizes into an adult, and digs its way out from the ground. Because it doesn't leave from the tree itself, it leaves no exit hole in the tree.

With colorful insects that have life cycles like this, it's amazing I am still able to focus on the plants!

Look What's Flowering Now!

We had some beautiful weather here in northern Indiana on Saturday, and I was able to take full advantage of it by botanizing at Sebert County Park in LaPorte County, Spicer Lake Nature Preserve in St. Joseph County, and Bendix Woods Nature Preserve in St. Joseph County. This is intended to be just a quick post to show some of the plant species that I saw in flower that Lindsay and I hadn't yet seen this year. For more information on several of these species, see my post here at Get Your Botany On!.


At Sebert County Park, I stumbled across American Dog Violet (Viola conspersa). This handsome blue violet is uncommonly encountered in moist woods, mostly east of the Mississippi River.
Limestone Bittercress (Cardamine douglassii) was flowering at Spicer Lake Nature Preserve. This plant of the mustard family (Brassicaceae) is commonly found in moist woods, often in somewhat disturbed areas.
The flowers of Limestone Bittercress have four petals, characteristic of mustards. This species is similar in appearance to Bulbous Bittercress (Cardamine bulbosa), but as you'll notice in the photograph below the stem within and below the inflorescence is pubescent, while that of Bulbous Bittercress has no hairs. There are also habitat differences, as Bulbous Bittercress is more often found in springy areas.
Also at Spicer Lake, Virginia Strawberry (Fragaria virginiana) had begun to flower on trails through an old-field. I later saw this somewhat weedy species, which can be found throughout North America, flowering on the trails on our property. This is a welcome site for Bootypants, who thoroughly enjoys plucking the Virginia Strawberry fruit right off of the plants as we walk our trails during the summer.
Bendix Woods will probably be at its peak for wildflower viewing next weekend, when I will be leading a hike there for Shirley Heinze Land Trust. However, several ephemerals were already in bloom on Saturday. One of those was Wild Ginger (Asarum canadense), which is found in moist woods throughout eastern North America.
The 1-inch long flowers of this gorgeous species are hidden below the leaves very close to the ground, and can be easily overlooked if you aren't specifically looking for them.
Lindsay recently talked about seeing Dutchman's Breeches (Dicentra cucullaria) in this post; on Saturday at Bendix Woods, I saw the closely related Squirrel Corn (Dicentra canadensis) just beginning to flower. The flowers of Squirrel Corn often have a soft pinkish tinge to them. The plant is named Squirrel Corn because of the tuberous roots, which are yellow and look like kernals of corn.
I really do enjoy seeing this next plant every spring. This is False Mermaidweed (Floerkea proserpinacoides), a plant of moist woods that is very easily overlooked and somehow often confused with bedstraw (Galium sp.).
The tiny flowers of this species have three whitish petals. You want to amaze your friends? Find False Mermaidweed in mid- to late-April and show them the beautiful flowers. Trust me... they'll be amazed. In the United States, this species is found as far east as Massachusetts and as far west as California.
And from one spring wildflower with three white petals to another...
This is White Trillium (Trillium grandiflorum), of the lily family (Liliaceae). White Trillium is the state wildflower of Ohio, and it's easy to see why. I've never come across someone in the woods who isn't completely enamored with this species. As the season progresses, the petals begin to turn pink. Next week, Bendix Woods should be a carpet of white, made up in large part by White Trillium.
Finally, I came across this little insect that I believe is a Click Beetle, though I have no idea to what genus or species it belongs. From what I understand, they are called "click beetles" because of their ability to snap two body parts together, which shoots them into the air to avoid predators.
This Click Beetle was perched on the spike of Plantainleaf Sedge (Carex plantaginea). If anyone can help with a positive identification of the insect, I would be love to know what it is.
More to come as the spring progresses!
By the way, the ticks are out, so watch yourself. Bootypants and I are tied at two each; Lindsay hasn't had any yet.

A Trip to Kaintuck Hollow

On our recent trip to Missouri, we spent the better part of a beautiful spring day at Kaintuck Hollow in Mark Twain National Forest. Below are a few photos of the fauna we saw... I could use a little help identifying a couple of these.

As soon as we got out of the car, I heard rustling of leaves and found a Blanchard's Cricket Frog (Acris crepitans v. blanchardi). In northern Indiana, cricket frogs have become pretty uncommon in the past quarter of a century; as you go farther south in the state, their metallic "gick-gick-gick" calls frequent the spring and summer air. The couple of times I have seen these inch-long frogs in the past, they have had an obvious green stripe down the center of their backs, like the one shown in my post here. Cricket frogs often have this colored stripe; sometimes it is red, yellow, or brown, but sometimes it is absent. You'll notice the warty texture to the skin, another helpful identification character. The feature to look for to obtain a positive ID, however, is the dark triangle between the eyes on the top of the head.

It wasn't long before I noticed another hop and commotion in the leaf litter, but this time the culprit was a russet-colored grasshopper. What a beautiful and well camouflaged creature! Thanks to Ted MacRae of Beetles in the Bush for identifying this as a Mischievous Bird Grasshopper (Schistocerca damnifica).

A bit later, while we were botanizing in an oak-hickory woodland, I saw movement out of the corner of my eye. After flipping over a few leaves, I found this approximately 1 inch long beetle. Thanks again to Ted MacRae for identifying this as a Ground Beetle (Carabus sylvosus).

Finally, we were lucky enough to see one of the Show-Me State's most unique mammals, the Missouri endemic Ozark Flying Squirrel (Glaucomys thomasii). This species bears little resemblance to the Northern Flying Squirrel (Glaucomys sabrinus) or Southern Flying Squirrel (Glaucomys volans), and in fact, unlike its relatives, is diurnal. Like its relatives, the Ozark Flying Squirrel shows an affinity towards lichens, acorns, and flowers.
