Look But Don’t Touch

Oil beetle of some sort, 19 April 2015, Linn Run State Park (photo by Kate St. John)

This indigo-colored beetle looks beautiful but I was careful not to touch him last Sunday at Linn Run State Park.  It’s a good thing I didn’t … and here’s why.

At an inch and a half long this beetle was hard to miss. Thirteen of us watched him walk on the leaves.  Loree Speedy suggested he was a Blister Beetle.

Wissahickon‘s bug expert, Monica Miller, confirmed he’s one of the many species of Oil Beetles (Melos) in the Blister Beetle family (Meloidae).  His true identity requires a coleopterist’s help but her guess is Meloe impressus.  (I like the idea that “This Meloe impressed us.”)

Blister Beetles earned their name because they excrete a poisonous chemical from their leg joints, cantharidin, that causes blisters on our skin.

Yes, he’s an amazing color, has short wing covers, knobby antennae.

Forewarned Is Forearmed

Clothes and dryer: The clothes dryer kills ticks (photo by Kate St. John)

After-hike defense: Dry your clothes before washing them. (photo by Kate St. John)

Yes, it’s time to get outdoors but remember there are dangers out there.

Not bears and mountain lions.  I’m talking about deer ticks, also known as black-legged ticks (Ixodes scapularis).  They transmit Lyme disease and it can ruin your life for a very long time.

Tick season never ends but it’s really dangerous in the spring and early summer.  Most Lyme disease is transmitted in May through July when the deer ticks’ tiny poppy-seed-sized nymphs are active and we’re active too.  We don’t notice the nymph, or we forget — or don’t know — the basics of protection against Lyme disease.

Here are the basics with great help from the TickEncounter website at the University of Rhode Island.

  1. Know the enemy.  Click here for details.

  2. Avoid the enemy. Click here for more.
    1. Wear light-colored long pants, long sleeves and a collar.
    2. Tuck your shirt in.
    3. Walk in the center of the trail. Before you walk off trail, tuck your pants into your socks and keep them that way.  Did you know ticks lurk in leaf litter, too?
    4. Pre-treat your clothing and shoes with permethrin (TickEncounter says this substitutes for (a) and (c) and works better than DEET!)
    5. Protect your yard and your pets with tips found here.
  3. Do a daily tick check.  Yes, daily!  You might have missed one yesterday.  Here’s how to check.
  4. When you take off your hiking clothes, immediately dry them for 10 minutes in a hot dryer.  Really.  This kills ticks.
  5. If you find a tick remove it correctly (here’s how) and save it for testing.  Send it here and they’ll tell you if it carries Lyme disease.

I thought I knew about deer ticks but I learned valuable new information at the TickEncounter Resource Center.  Visit their website here.

Forewarned is forearmed.

Even with permethrin, don’t bushwhack through Bush honeysuckle or Japanese barberry.

The Sound Of Peepers and Woods

Published by under Insects, Fish, Frogs

Last Tuesday afternoon the frogs at Raccoon Creek State Park Wildflower Reserve in Beaver County, PA were singing up a storm so I recorded them with my cell phone.

The loud peeps or “crrrreeeep” sounds are spring peepers.  The low mutterings or quackings are wood frogs.

There are so many wood frogs in this audio that you can’t hear individuals.  There are so few spring peepers that you can hear each one.  There might be more species here but I don’t have the ear to hear them.

Check out this list of western Pennsylvania frogs for more possibilities.

Sounds of Spring: Frogs!

Published by under Insects, Fish, Frogs

Have you heard any frogs lately?

In early spring male frogs call from ephemeral pools to attract females to mate with them.  This week in Frick Park I’ve heard spring peepers calling in the wetland next to Nine Mile Run.  The sound is so miraculous in the City(*) that I always stop to absorb it.

Spring peepers are loud but so tiny I couldn’t find them.  Look how small they are compared to someone’s hand!  Needless to say I didn’t see the “singers” in Frick Park.

Peepers aren’t the only ones calling.  Right now you can hear wood frogs and others if you’re in the right habitat.  But which ones?

PA Herps does statewide surveys to confirm the ranges of Pennsylvania’s native frogs (and much more).  Based on the PA Herps Frogs and Toads List I made this table of the frogs and toads that still occur in western Pennsylvania west of the Allegheny Front.  I added my own description of the calls I know.  Click here on the PA Herps website to look up each frog including their photos and range map.

Frog Name Description of Call
Eastern American Toad, Anaxyrus americanus a whirring trill
Fowler’s Toad, Anaxyrus fowleri  *
Cope’s Gray Treefrog, Hyla chrysoscelis  *
Eastern Gray Treefrog, Hyla versicolor  *
Bullfrog, Lithobates catesbeianus a low ‘hrrrrmp’
Green Frog, Lithobates clamitans a tuneless banjo twang
Pickerel Frog, Lithobates palustris  *
Northern Leopard Frog, Lithobates pipiens  *
Wood Frog, Lithobates sylvaticus sounds like ducks quacking
Mountain Chorus Frog, Pseudacris brachyphona  *
Northern Spring Peeper, Pseudacris crucifer LOUD! peeps, jingle bells -or- plinking the teeth of a comb
Western Chorus Frog, Pseudacris triseriata  *
Eastern Spadefoot, Scaphoipus holbrookii  *

* See the comments for frog call descriptions from Sue.


To hear them, look them up here on the USGS Frog Quiz website.   (Your computer must have QuickTime installed.)

If you know a lot of frog calls you can test your skills at the USGS Frog Quiz here.  Don’t feel bad if you don’t recognize the calls. I tried the quiz and flunked immediately.  As you can see by the gaps in my table, I don’t know many frog sounds.  It’s time to get outdoors and remedy that!



Can you add frog call descriptions to my table? Leave a comment with your description.  *Thank you, Sue! See her comments.

* The miracle in Frick Park is a complex of meanders and wetlands completed in 2006 by the Nine Mile Run Watershed Association and U.S. Army Corps of Engineers.  Spring peepers found the wetlands on their own and now loudly pronounce them good for breeding every spring.

Roseate Tern chasing Common Tern at Petit Manan Island, Maine (photo by USFW via Wikimedia Commons)

On Saturday’s blog, red+white made pink.  Today, pink makes for roseate names.

The roseate tern has been called the most beautiful tern on earth for his pale rose-colored breast and long fluttering tail streamers.  In the photo above, a roseate tern (Sterna dougallii) chases a common tern at Petit Manan Island, Maine. Look closely and you can see the pale pink blush on the tern in the foreground, so pale that the color is not one of its field marks.

The beautiful bird has a good reason for chasing the common one.  Roseate terns are listed as endangered in the Northeast and where both species nest, such as Petit Manan, the common terns push out the roseates.

The roseate spoonbill (Platalea ajaja) is a South American bird whose U.S. population was decimated during the plume-hunting era.  Now that its carmine, orange, and rose-colored plumes are no longer used for hats, it’s made a modest comeback in Florida and the Gulf Coast states. In Chuck Tague’s photo you can’t see the bird’s orange upper tail but you can see why its name is “roseate.”  What a pink bird!

And finally, even a dragonfly can be rose-colored.  The roseate skimmer (Orthemis ferruginea) ranges from the southern U.S. to Brazil and has been introduced in Hawaii, perhaps because it’s beautiful.  Chuck Tague photographed this one in Florida.

Though their shades of pink are not the same, all three deserve a roseate name.

Hemlock woolly adelgid at Jacobsburg (photo by Nicholas A, Tonelli via Wikimedia Commons)

Yesterday I mentioned hemlock woolly adelgid, a really bad invasive insect that’s killing our eastern hemlock forests.  It devastated the southern Appalachians (click here to see, here to read) and has moved north into south, central and eastern Pennsylvania.  Has it conquered the Allegheny High Plateau?  Now’s the best time to find out.

Hemlock woolly adelgids (Adelges tsugae) have no North American predators and a very unusual lifestyle.  Originally from Japan, they kill eastern hemlocks in 4-20 years by locking onto the underside of their branches and sucking the lifeblood out of them.

The adults are female, immobile and practically microscopic.  Twice a year they reproduce asexually, laying up to 300 eggs a year in woolly white egg sacs that protect their young.  The larvae, present in April and July, are the only mobile phase and so tiny that they spread easily on the wind or hitchhike unseen on birds, animals and humans.
Hemlock wooly adelgid adults (photo by Ashley Lamb, Virginia Polytechnic Institute and State University,

Harsh winters used to protect Pennsylvania’s hemlocks but the climate is warming.  Our worst fears were realized when they were found in Cook Forest in March 2013.  Last winter’s Polar Vortex reduced that infection 90-100% but the bugs are poised to take off again. Unfortunately the only biological control, a tiny beetle, is even less winter-hardy than the pest so the only way to save our hemlocks right now is by treating individual trees with pesticide. (*)

What trees should be treated?  The Nature Conservancy, the U.S. Forest Service and DCNR have teamed up to survey the area from Cook Forest to New York’s Allegany State Park (click on this map to see a larger version).

Priority hemlock conservation areas on the Allegheny High Plateau (map from The Nature Conservancy and US Forest Service)

It’s a big area and they need your help.  Don’t worry, it’s easy.

In the winter hemlock woolly adelgid egg sacs are large and visible (see top photo).  If you’re in this region — even for a quick hike or birding trip — take a moment to notice the underside of hemlock branches.  Birders, you may accidentally find this while looking at a bird.

Report infections by calling or emailing the location to one of the folks on this list of contacts.  (Contact any of them and they’ll forward the information if necessary).

Do you need more information before you begin?  Contact Sarah Johnson at The Nature Conservancy,, 717-232-6001 Ext 231.

Spider Whisperer?

Published by under Insects, Fish, Frogs

Kate St. John holding a tarantula (photo by Dianne Machesney)

Look at what’s walking on my hand!

On the night before Halloween at Wissahickon Nature Club Sarah Lyle taught us about Pennsylvania spiders and showed us her pet tarantulas.  Three of them were very tiny but two were … huge!

I am not a spider lover but Sarah’s enthusiasm for them is infectious.  When I first saw her tarantulas I thought, “No way will I handle one of those!” but by the end of the evening I did.

Dianne Machesney, who took this photo, called it “the fearless spider whisperer.”


My look of concentration is not spider whispering.  It’s intent focus on one thought:  “Do not do anything to upset this spider!”

Two of the hands in the photo are Sarah’s, gently corralling the tarantula so it doesn’t walk up my arm.

Moth Identity Challenges

Published by under Insects, Fish, Frogs

Moth found in Harrison Hills County Park, Allegheny County, 23 Oct 2014 (photo by Kate St. John)

Yesterday I photographed this half-inch-long moth at Harrison Hills County Park near Natrona Heights.

This morning I tried to identify it at using the online photos.  I was able to narrow my list to 20 possibilities out of more than 3,000 moths but none of them were correct when I compared closely.

Changing tactics I used the regional perspective:  Which of my 20 possibilities were on the Allegheny County moth checklist?  The checklist subtracted 10 and added four.  However, my faith in that checklist was shattered when I discovered it’s missing Malacosoma americanum, the eastern tentworm moth, that Tom Pawlesh photographed in Allegheny County and posted on the website.

Nonetheless the checklist gave me a hint.  Perhaps this is one of the owlet moths, Noctuidae.  It looks a bit like Eupsillia tristigmata.

Searching through Noctuidae at I found one here that looks like mine but no one has identified it.


Perhaps you can tell me what it is.  Please leave a comment with your answer.

p.s. Fascinating news on Monday Oct 27:  Owlet moths pollinate witch-hazel flowers at night!

UPDATE 25 July 2015: This moth may be the Dotted Sallow moth (Anathix ralla)
