  1. Sorry for the delay in responding... Looks like a species of Brachycentrus (Trichoptera: Brachycentridae). Larvae often suspend their cases into the current, from which they filter feed (using fine setae on the forelegs) course- and fine-particulate organic matter.
  2. I would bet that this nymph was in a stream that had a considerable amount of groundwater. Groundwater contained in the aquifer is anaerobic, and thus dissolved iron (Fe+2) is in the reduced form. As groundwater is released in an unrestrained environment, it's oxidized, either through contact directly with dissolved oxygen, or through its use by bacteria that utilize the reduced iron for metabolism. Oxidized iron then shows up as flaky reddish or orange particulates. Cheers, Ethan
  3. Hmmm, looks like a Stenonema/Maccaffertium. Roger, any thoughts? The nymph looks like Ephemerella.
  4. Regarding not being any Neuroptera being aquatic, this is from my web page on aquatic Neuroptera (Aquatic Insects of Michigan): Cheers, Ethan
  5. You need to specify the aquatic insect and the type of aquatic system into a web search engine. For example, type in "aquatic insects" + lakes, and you'll get links from pages that have information (somewhat) matching these criteria. Probably a better strategy would be to specify the group of aquatic insects and the type of, or name of, marsh/bog/pond/lake. For example, "trichoptera" + "bogs" yielded this result: [PDF] Caddisflies(Trichoptera) of Ohio Wetlands as Indicated by Light ...

As you probably know, you can also narrow down your search by locality by adding more search criteria. Other than that, I'd have to refer you to the printed literature. Hopefully this helps. Cheers, Ethan
  6. Will, Generally light-trapping for stoneflies yields meager results, and captured specimens are probably accidental rather than an individual exhibiting positive phototaxis. If you wish to use a trap, it's better to use a Malaise trap, details of which you can get off the web using a search engine, or just checking rocks, stream-side structures, and bark, or doing sweep netting of stream-side vegetation. Light-trapping (particularly UV, which you can buy at a hardware store), on the other hand, will yield many more mayflies, and it's often the preferred method of sampling the short-lived adults. Cheers, Ethan
  7. The "controller"? You mean your boss, or your wife? Or both?
  8. Like I posted some time ago, the information contained should be updated through mid-2007. Considering the Third Edition came out in 1995 (i.e., the information was probably good through some part of 1994), it's a 13 year update. And, in science, that can be a long time. Consider also the following updates: 1) Keys are updated, not only with the taxonomic changes but many new characters; 2) New taxa considered aquatic or semi-aquatic are included, which is important for the Diptera and Coleoptera, as well as other groups; 3) There's a color-plate introduction to the families; also there are B/W photos of caddis cases in the Trichoptera genera chapter; and 4) Ecological information (and tables) and bibliography have been updated, which for me is a BIG plus. There are lots of improvements in this volume, and with (hopefully) most of the errors now corrected, I can recommend it. Finally, you are absolutely correct that Kendall/Hunt's upping the price to $125 (which you are probably correct in surmising that is an attempt to cover the $100K or so costs involved with this new printing) is a little disingenuous. As I've stated before, I'm a little ticked off that what I bought was a "beta" book, something that was NEVER advertised, especially by Bio-Quip (from whom I purchased my copy). On the other hand, my copy was sold at a 10% discount, so I wasn't charged for the $35+ increase or for the shipping costs. Unfortunately, it's the new customers who'll have to pay the costs. All that said, it is still a GREAT book, and since you seem a very SERIOUS aquatic insects person, I'd recommend purchasing the book sometime in the future. You might want to check with Bio-Quip or elsewhere to see if they are selling the book at a discount. Cheers, Ethan

  10. Well, that was fast. I received the new copy (I guess the "gamma" version) yesterday, and it seems if a lot of errors have been corrected, including misprinted figures and errors in the keys and tables. Kendall/Hunt also quickly sent me a UPS shipping label to return the "beta" version of the book (i.e., no charge for return shipping). So far, so good! Cheers, Ethan
  11. Don't know the parts? Here's your picture, adapted with Photoshop (hope you don't mind), with some body parts identified. Cheers, Ethan
  12. As a follow-up to my previous post, I just called Kendall/Hunt (KH) regarding the replacement. Because I purchased my copy from Bio-Quip, KH charged my credit card for the new copy of the book. With the shipment is a mailer packet included, so that one can mail free-of-charge the old (defective) copy back to KH, who then will credit my credit card for the cost of the new copy (plus any additional charges). This is to prevent cheating KH by one keeping both new and old copies. If you bought your copy directly from KH, I assume you'll have a different experience. I'll try and post a further follow-up on my experience with the replacement, and a short review of the "revised" book (i.e., see if all the errors I've noticed have been corrected). Additional comment: In KH's announcement, I was a bit annoyed that they referred to the first printing as a "beta". This is the first time I've ever purchased a "beta book," especially one that cost almost $100; in fact, I don't recall myself having purchased beta software. If that was their beta, I hate to see what the alpha looked like! Well, it appears I'm now getting the gamma version: I hope I don't need to purchase a delta version, much less any further Greek letter versions of the book. However, I wish to end this on a positive note. The people at KH who answered the phone were very courteous, and the woman who answered wrapped up the replacement order in less than 10 minutes. KH is to be commended for offering to replace the book (acknowledging their screw-up) at no charge, indicating the company does care about the customer. (At least those buying this book). It is a great book, and I still highly recommend it - it is the BEST aquatic insect book for North America, and as of 2007, it's up-to-date.
  13. Dear Colleagues: Dr. Marty Berg, one of the editors of the Merritt et al. 2007, "Aquatic Insects of North America, 4th Edition," has sent a message to me today that Kendall/Hunt, the publisher, will now be processing replacement orders: Message to Purchasers of 4th edition (2007), first printing of “An Introduction to the Aquatic Insects of North America” by Merritt, Cummins, and Berg from Kendall/Hunt Publishing Company Thank you for your purchase of AN INTRODUCTION TO THE AQUATIC INSECTS OF NORTH AMERICA by Richard W. Merritt, Kenneth W. Cummins, and Martin B. Berg. This message is to notify you that the above book (4th) edition has been reprinted and Kendall/Hunt is now offering to replace your beta version with a new updated printing at no cost to you as a purchaser. The beta version you now own contains significant errors in both content and printing and should not be used. These errors have been corrected and thus the reason for the updated reprinting. Please contact Kendall/Hunt's Customer Service Department at 800-228-0810 for instructions about how to receive this new printing, ISBN 978-0-7575-5049-2. We sincerely apologize for the inconvenience, and we trust that you will be pleased to trade your beta version in for the updated printing. Sincerely, Richard W. Merritt Kenneth W. Cummins Martin B. Berg
  14. If you can get a detailed (say 5-10x) photo underneath its head (view of the prementum), one might be able to tell whether it's a species of Calopteryx or Hetaerina. I have a picture of the difference at: http://insects.ummz.lsa.umich.edu/MICHODO/test/calopg1.jpg. You can also use my key at http://insects.ummz.lsa.umich.edu/MICHODO/test/Calopdae.htm. Cheers, Ethan
  15. I agree with Roger - T. nivalis. However, when they emerge (if they're still alive), which should be anytime soon (they have a late winter, early spring emergence), the adults (especially males) will provide definite proof of identity. Cheers, Ethan
