Leafminer e-book now available on a sliding scale

Hi everyone,

In the interest of making leafminer identification more accessible, you can now get the first edition of the Leafminers of North America e-book for as little as $5 US. For details, see today's BugTracks post.

Online seminar - Leaf and Stem Mining Insects of the Southern USA

On Thursday evenings from April 29 to May 27 I'll be offering a "Leaf & Stem Mining Insects of the Southern USA" online seminar. "Southern" is anywhere that spring is far enough along for there to be plenty of leaf mines to observe! Details here.

Attention leafminer hunters!

Until further notice, I am offering a free subscription to the 2nd edition of Leafminers of North America to anyone who sends me material of western grape Phyllocnistis suitable for DNA barcoding (i.e., larvae, pupae, or reared adults; not just empty mines--but a mine with a dead, dried larva inside may work). I'm after the mines with the distinct narrow central frass line, like this one:
So far they have been found in California, Utah, Colorado, and Arizona (in one case on Parthenocissus, which I'd happily accept too). Although this mine type is my primary target, I'll accept western examples of Phyllocnistis vitegenella (the "snail trail" one) for now too. By western I mean west of the Great Plains.

And so people east of the Rockies don't feel left out, I'll also extend this offer to anyone who can collect mines containing larvae (dead or alive) of the mysterious nepticulid moth on dogwood (Cornus spp.). The mines are entirely linear and look much like those of Phytomyza agromyzina at first glance, but the frass is in a central line rather than alternating along the sides, the larva will have a distinct head capsule, and there will be a tiny, shining eggshell at the beginning of the mine (possibly on the lower leaf surface). I don't think I've seen any examples on iNat yet, but empty mines have been found in Ontario, Iowa, Ohio, and Vermont. Here is one I found in southern Ohio on August 6 a few years ago. That's my only datapoint as far as when an occupied mine can be found; the few other examples have been found later in the season, already empty.

If you think you've got what I'm looking for, post the observation and message me!

Leafminer common names

Hi everyone,

A friendly reminder that the curator guide says "try to add names at the taxonomic level where they describe all members of that taxon and only members of that taxon. If a species has no common name in usage, please don't make one up."

Very few leafminers have established common names, and there are a lot of examples of newly made-up ones on iNaturalist. Often they take the form of "[host plant] leafminer." Since there is hardly any plant with just one species of leafminer on it, this practice leads to many absurdly wrong IDs (and frankly the same problem exists with most of the "official" common names that do exist for leafminers). I'm starting to delete these bogus names as I come across them, now that I've figured out how to do it. Please don't introduce any new ones.

All caught up!

Hi everyone,

Nearly a year after creating it, there are now 5583 observations in the North American Leafminers umbrella project (https://www.inaturalist.org/projects/north-american-leafminers), and I've just finished reviewing all of them. A couple of notes:

I think that's it for now. Keep up the good work!

Welcome to Leafminers of North America

Hi everybody!

Thanks for adding your photos of leaf mines to this project. Just a few hours in and there are already over 600 observations! I wanted to mention a few things in addition to what is in the "About" section:

  • If your photos are already part of a regional leafminer project, there is no need to add them here, since I've created an umbrella project to keep track of them all: https://www.inaturalist.org/projects/north-american-leafminers ...If you are aware of others (or decide to start one), just let me know and I'll add them on.
  • There is lots left to learn about leafminers, so if you encounter mines that can't be identified, I encourage you to try rearing them to adults. My rearing methods are outlined here: https://bugtracks.wordpress.com/rearing/
  • For a complete accounting of what leafminers are known from every plant in North America, including mysteries that need further investigation, see my Leafminers of North America e-book: http://charleyeiseman.com/leafminers/

There are well over 2000 species out there, and the umbrella project currently registers 119, so let's see how many more you can find!
