YES! Finally found some!

[vfox]

I'm just excited, I've finally found some local (backyard) Parcoblatta pennsylvanica cockroaches. These guys are supposed to live on/in old bits of wood and under bark etc...guess where I found them? Under scrap steel siding from my barn! I was out for about 2 hours digging open stumps and logs in the woods because it's about 54ºF today. I figured, what the heck, I'll give it a shot...although I've never had any luck before. I was about to give up and passed by the siding pile and thought, eh, maybe I'll find some spiders or something. I lift up the first sheet...nothing, second sheet...small spiders and a few ants, third sheet...almost two dozen roaches scurrying away! I was completely taken off guard and clamored for my tube. I picked it up again and grabbed as many as I could before they vanished in the grass. I'm very pleased about this, I've been looking for these guys for a pretty long time. Okay so I'm not 100% certain these are P.pennsylvanica yet but they are certainly a good candidate considering I live near the woods and have never seen a German or American cockroach in any home in my neighborhood.

Woooo! Congrats!

Only recently have I started finding Parcoblattas around here; I've been finding another small species (Ectobius pallidus) for a while now but the cultures just won't take.

You might have a mix of Parcoblattas there; you'll have to wait til they mature to find out.

P. pennsylvanica are really fun... I have one female who produced maybe 70 babies even though her mate died a few days after she molted to adulthood!

As I understand it there are Blattella germanica, Supella longipalpa, Parcoblatta pennsylvanica, Parcoblatta virginica, Parcoblatta fulvescens, Parcoblatta divisa, Parcoblatta lata, Periplaneta fuliginosa, Periplaneta americana, and rarely Periplaneta brunnea around here in PA. I'm hoping to find more this spring/summer but it will be a good thing to see if the ranges listed are actually true and all of these are native to PA. Basically PA wood, Southern wood, German, and American are a good certainty anyway.

Wow you got a lot of them. My colony started from just two individuals. They are very fun roaches. Keep us updated on their progress

Yeah I found 14 total so I'm really pleased about that. I've been looking for these guys for such a long time; they are my first WC roaches. I can't wait for them to mature though, I've been wanting to expand the general knowledge of these guys for a while since I'm a native Pennsylvanian, lol. Honestly though I think they are really understudied and not much seems to be available on them so hopefully I can make some useful observations. At anyrate...they are pretty neat so I'm just happy to have them.

 

[Vulgaris]

Looks like you may have a few species there. Were they all found in one group? I am in PA too. Seems to be a great state for wood raoches. Once my colony becomes fully interdependently breeding, I am going to mix in the orange species too. Can't wait to see how yours turn out!

 

[vfox]

I found them all together and I'm fairly certain they are all the same kind of roach. There is no certainty until they molt into adulthood though. There is a small possibility that they are Blatta orientalis but that species is pretty rare around here and wouldn't likely be active at this time of year.

What part of PA are you in btw? I'm in south central York county about 20 minutes north of Maryland. The Susquehanna valley region I'm in gets pretty cold but we still get a huge range of fauna around here. I've seen things that should only exist in the south and things that should only exist in canada come through here. It's a good place to be for most eastern species of well...almost anything lol.

 

[Vulgaris]

I am about 25 min SE of Harrisburg. Probably only an hour or two away from you

If they were all found together, it is highly likely they are all the same sp. You wouldn't see orientalis outside like that. Those are certainly Parcoblatta. I often find the orange nymphs overwintering in groups like that. I am going to throw in any that I find this winter with my pennsylvanica colony

 

[Ralph]

I love Parcoblatta. You've got a couple subadults in there, but as I've said they grow so slowly so ID'ing might not be imminent. Absolutely worth the search and patience!

 

[vfox]

Vulgaris, youre likely less than a half hour away if you're south east of Harrisburg. Unless you mean really east like in Lancaster lol. Do you find them often btw? These are honestly the first wild roaches I've ever seen around here.

Ralph, I really hope these are P. pennsylvanica lol. I don't mind if they are the southern ones either though. Time will tell. They are very active little guys though, very similar to my Blatta lateralis. I'm quite enjoying having them.

 

[Vulgaris]

yeah you're probably pretty close. Lancaster is south of me.

I never used to see these roaches very often, but in the last few years I have been finding a lot. I collected a hornet nest recently, and 5 Parcoblatta nymphs came out of it. I have also been seeing them in logs and such. I cant wait to get my colony into a new enclosure next week

When I went to Millersville the only thing I ever saw there were the occasional German cockroaches. I have crap luck when it comes to finding interesting species; it's why I'm so excited I had found these. I would love to find like 50 more though lol...maybe in the spring I'll get lucky. At least I know I can get all the pest species I want from York city...plenty of them running about...no Parcoblatta though.

 

[Vulgaris]

Raise these 14 nymphs to adulthood, and you WILL have 50 or more. lol

I went out last night, it was 28 F and lo and behold I found 4 more nymphs lol. I think that may be the end of the aggregation under the metal but it brings me to 18 total. Now that I know they are around though...come spring I'm going to use light traps and flashlight night hunting.

 

[Zephyr]

I have a female Parcoblatta sp. (Probably virginica but maybe lata) who's about 5 months old now. I have no idea how many ooths she's laid but there are easily 50 nymphs in the container. It's impressive how many babies one of these roaches can make. lol

 

[Vulgaris]

i didn't know you were also raising them, Zephyr. Got any pics?

 

[Zephyr]

Here are some pics of the original two females I had:

Potential P. virginica. She's still going after 5 months.

Potential P. uhleriana. She died after a month in my care. Fortunately she laid many, many ooths and I now have 40 or so babies from her.

I took these shots today along with some others I posted in my Hisser test image thread in the photo gallery.

So I went and dug open another log deep in the woods yesterday and I found an amazing plethora of critters. I found so many click beetles and metallic sweat bees that I really lost count, one bald faced hornet queen (which I accidentally cut in half when I split the chunk she was in), and a bunch of Camponotus spp of carpenter ants...and this is the odd part, only inside the ant tunnels did I find 40-50 young nymphs of Parcoblatta pennsylvanica wood roaches. I figured I would find them underneath the log or even in old tunnels no longer used but they cockroaches were living in the tunnels, literally on top of the ants. I found this pretty odd, anyone else every notice a cohabitation like that?

Here is the container of P.penn and some click beetles. Many many roaches are hidden in this image, there are loads more.
