A week ago this moth stood out at Oil Creek State Park with an impressive brown pattern on his white wings.

I sketched the moth in my notebook while Karyn Delaney took its picture (above). When I got home I found a tool to help me identify it: Discover Life’s moth ID Guide for Pennsylvania.

My search of the moth’s basic characteristics produced 62 answers (!) but I clicked through each pop-up until I reached one that was similar but not the same.  The yellow-orange head was a useful clue.

LeConte’s Haploa moth (Haploa lecontei) is known to have a variable pattern.  The photos below compare a plainer version to our own (super-magnified). has this closeup of one that looks like ours.

I’ve heard of LeConte’s sparrow and LeConte’s thrasher (though I’ve never seen them) and wondered if this moth was named for the same LeConte.  Indeed it is.

John Lawrence LeConte was a famous 19th century entomologist from Boston who traveled the U.S. in search of bugs.  Beetles were his specialty but he identified many other species as well.  According to Wikipedia, he “described approximately half of the insect taxa known in the United States during his lifetime.”  He was greatly admired in the scientific community.

When scientists name a new species they sometimes use a person’s name, either the name of someone they admire or someone connected to the discovery. Audubon admired LeConte and so named the sparrow, LeConte himself discovered the thrasher (someone else probably named it for him), and this moth was named for the same LeConte.

Too Many Ticks? Hire a Possum

Virginia opossum (photo by Drcyrus from Wikimedia Commons)

Pennsylvania won an award again though there’s no reason for applause.  For the third straight year we lead the nation in reported cases of Lyme disease.

One could argue that we won because Pennsylvania is a big state with a large population, but we also have too many black-legged ticks, too many tick hosts that carry Lyme disease (mice), and too many deer carrying ticks long distances to other locations.  Black-legged ticks are now present in every county in the state.

What to do?  In April I wrote about the many effective ways to reduce ticks around your house and protect yourself outdoors.  But here’s an unconventional solution.  Get yourself a ‘possum.

Like all mammals, Virginia opossums pick up ticks in their travels but the good news is that they don’t carry Lyme disease and they groom so meticulously that ticks don’t stay on them for long.  In fact, when a possum finds a tick on its body, it eats it!

Weird as they are, possums have some advantages.  They consume up to 5,000 ticks in one season and are practically immune to rabies and venomous snakes.

So as we do our best to combat Lyme disease — especially in May through July when black-legged ticks are so hard to see in their tiny nymphal stage — remember that having a possum in your yard is a good thing.

Too many ticks? Hire a ‘possum!

Little Eats Big … Slowly

We’re used to top predators eating small prey but the world is far more complicated than Big Eats Little.  Small things can weaken a predator or bring it down.

Harvestmen (Opiliones), also called daddy long-legs, are omnivorous ‘bugs’ distantly related to spiders.  They are harmless to humans but can be dangerous to small insects.  However they can be weakened by even tinier parasites.

See those two red dots on the harvestman’s legs?  They are parasitic mites sucking the harvestmen’s “blood.” identifies them as a species of Leptus (family Erythraeidae) whose larvae parasitize North American harvestmen.

Just two mites are probably not a problem but a large infestation on the body weakens the harvestman.  If seeing bugs-on-bugs doesn’t bother you, click here for an example.

Harvestmen clean their legs by drawing them through their jaws so it’s a wonder the mites remain in place.  Obviously there’s been a long mutual evolution of cleaning and clinging that brought these two species to where they are today.

No matter how small the predator, there’s always something smaller to oppress it.

Red Admiral

Guess what I found sipping nectar last Sunday …

With my head so full of birds I couldn’t remember this butterfly’s name so I took a lot of bad cellphone photos (below) and looked it up when I got home.

This striking black butterfly is a Red Admiral (Vanessa atalanta), native to Central and North America, Europe, Northern Africa and Asia.  That’s why the beautiful photo above is from England.

The species is not winter-hardy so most of North America must be recolonized each spring by southern migrants, says   Monarchs aren’t the only butterflies who make long journeys.  Red Admirals migrate from South Texas and I’ve seen them fly north over Lake Erie to Canada.

The generation that migrates looks brown where this one is black so they don’t stand out as much.  Their underside is not as pretty either but provides camouflage (click here to see).

We don’t often see Red Admirals in flower gardens because they prefer to eat tree sap, fermenting fruit and bird droppings(!).   The females look for nettles where they lay their eggs on the tops of the leaves.  The caterpillars eat nettles to survive.

Take that, you stinging nettles!

Got Bugs?

They’re back!!!

Billbugs are everywhere and they’re freaking people out. Are they dangerous? Are they ticks?

No.  They’re harmless.  They don’t even bite.

Read all about them in last year’s blog post: Invasion of the Billbugs

p.s.  Ben Coulter and Monica Miller have identified this weevil as Odontopus calceatus, a.k.a. Yellow Poplar Weevil, not Curculio as I read in the paper last year.   Don’t believe everything you read in the paper!

Snakes In The Grass

If snakes give you the creeps close your eyes.  I’ve placed my poor quality photo at the top so you have time to stop looking.

Last Saturday near Duck Hollow a cyclist stopped to tell me there was a big snake by the trail.  He said he could tell by my gear that I was interested in nature and would want to know.  (I must look like someone who approaches snakes.)

I’m glad the cyclist told me.  The sunning snake was four feet long and very twisty as if it had wrapped tightly around a sapling and was unable to straighten out.  I know almost nothing about snakes but guessed by the shape of its head and round eyes that it wasn’t venomous.  Why twisted?  I posted my photo at the PA Herps Facebook page to find out.

Pam Fisher identified it as a black rat snake and said that snakes sometimes make their bodies twisty to break up the visual pattern.  For this snake though, his camouflage trick attracted attention.

I don’t look for snakes so the ones I find really have to stand out.  For more than 20 years I’ve visited Jennings Prairie to see the birds and wildflowers but have never seen its famous endangered resident, the Eastern Massasauga rattlesnake.

Dianne and Bob Machesney have visited Jennings much more than I have and they’d never seen the rattlesnake either until…  On June 4 they found a rattlesnake sunning, close enough for a zoomed in photo.

Dianne wrote, “After all these years, this is the first time we saw an Easter Massasauga Rattlesnake in the wild. The field had recently been mowed and she was sunning herself.  The milky eyes mean she is getting ready to shed.”

Perhaps cool mornings in early June are the best time for seeing snakes in the grass.

You can open your eyes now.  😉

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.

Just look. Don’t touch.

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.
