I forgot about the potential desire to see specimens. I have seen these galls in at least three locations in at least two Minnesota counties (Jackson and LeSueur) in the past two years (July and August as I recall). If someone wants specimens, please let me know. I should be able to secure specimens next year.

on most prairie remnants in Iowa but have yet to see them on a prairie planting.

I do wish someone could rear an adult. I have never been able to rear an adult fly, no matter when I collect the galls, although have gotten an occasional parasitoid but am not sure if it was from the same type of gall (see for gall question).

I just noticed that I did see these galls in a restoration this July. However, it is a reasonably small restoration with a high density of lead plant which is a adjacent to remnant prairie in Joseph A. Tauer Prairie SNA. Also present were Walshia amorphella galls and - all on planted lead plant. I have yet to see them on a stand-alone restoration.

Thanks for the info that you've found both the galls and W. amorphella in a prairie planting.

Also, would certainly welcome you trying to rear the lep larva. I've tried several times with a successful rearing to adult (moth) only once

Third thing: have you found these on Lead plant in a planting?

OK, fourth: how about these ?

Thank you for providing me with information through the work you put on BugGuide.

Many of these insects are somewhat of a tangent for me, not my principle focus so I do very little rearing. I also do most of my observation on sites where I need permits to collect - some places I have permits for some species, most of my collections come from my limited time on private property.

Regarding the Amorphicola pallida. I am not sure I have seen that species anywhere; however, I suspect I would easily over look it. I am amazed how many times I am going through plant photos and there are insects or spiders of that size that I did not notice in the field. I generally do not pursue them as I have limited photos, but I do not recall seeing that species or anything like it on lead plant.

More interesting to me is item #4. I do not recall seeing anything similar in a restoration, but it doesn't mean I haven't. Sometimes I do not realize I am in a small restoration in a larger remnant complex. I have collected something similar from a dry hill prairie in Yellow Medicine County, MN. I have pressed specimens of the leaves and a preserved larva in EtOH which I hope to send to Ray Gagne as soon as I get through my photos and permit reports. I was not aware that you had previously encountered that species [group?]. I will send you some images and additional information by email.

I also raised a parasitoid from the galls this year, but so far no luck with midges. I collected these galls from several locations as far northwest as western Yellow Medicine County this year (about as far NW as I have searched), but I lost most material due to mold issues before anything emerged. I also have not noticed these galls on "restored prairie", but I do not spend much time on restored prairie. I also really wondered if the two gall shapes were different species, but minimally they do seem to co-occur. I also found similar galls (the conical form) on flowers this year in at least two counties (I fear I may have deleted the photos, but I have a specimen).

I've been rearing for years and still fail more than I succeed. I find there is a fine line between desiccation and rot and I have yet to master it.

As far as I know, nothing further has been learned about this species, and there are still no specimens of larvae or adults.

Thank you very much for the information. That is very interesting. I will see what I can do - I will be looking for them next year.
