Linear mine, Polymnia - Liriomyza hypopolymnia

Trout Run Trail, Winneshiek County, Iowa, USA
July 5, 2017

06/30/17 Collected leaf with conspicuous blotch mine on Polymnia

A few days later -- larva from blotch mine fails to pupariate properly, but another puparium turns up in the rearing container...I take a closer look and discover an inconspicuous linear mine on the underside of the same leaf, from which the puparium appears to have emerged

07/05/17 Photos of puparium and leaf mine

Adult emerged sometime in the next few weeks; I don't have the exact date with me at the moment

07/21/17 Photos of spent puparium and adult

C. Eiseman found similar lower-surface linear mines, and also upper-surface blotch mines, on Polymnia during his visit to northeastern Iowa in 2016.

Just checking.

The blotch mine with the distinctive curves in this photo is different that the linear window pane mine in the second photo, correct? I just collected the linear mines a couple of days ago, some larvae still feeding but some have pupated having emerged on the upper side of the leaves. I really like the linear feeding pattern.

… MJ Hatfield, 24 October, 2017 - 10:56pm

Yes

The blotch is Nemorimyza posticata and the linear one is a mystery Liriomyza; some more reared adults would definitely be good.

… Charley Eiseman, 24 October, 2017 - 11:36pm

By the way,

I just collected a bunch of these blotch mines in Tennessee, and I think they're Nemorimyza posticata, but I'll wait until I have adults to be sure. I found a number of the Liriomyza (underside linear) mines too, but all empty. I got pretty good at spotting them from above--they cause a slight discoloration on the upper surface--but that may only happen after the mine is abandoned.

Hey, nice

Hadn't heard of Nemorimyza posticata before. Looking at the images on BG I see it makes small blotch mines on goldenrod leaves too -- which appear to be the same as something I collected earlier this year and reared successfully (haven't posted to BG yet though)!!...cool that it may be the same critter.

Speaking of not posting things to BG yet...I'm so overwhelmed, Charley. My head is full of all the things I've been learning from my rearings this year (dozens of successful rearings, mostly of flies and beetles and small moths, not to mention things learned about larval stages even when rearings failed), and I want to share it all, but the prospect of doing all the work it will take to share this information is daunting, to say the least. You know the feeling?

… John van der Linden, 24 August, 2017 - 10:32am

I do

I look forward to seeing what you've got when you get around to posting it. I'm still back in early March in my photo sorting.

… Charley Eiseman, 31 August, 2017 - 8:16pm

Nice!

These are the two mine types I found. This fly is almost certainly a Liriomyza. The tip of the abdomen is obscured, so I'm not sure of the sex--hope it's a male!
