Lois - If I might add one thing, I suspect that most people check only the live plates on MPG (those buttons on the right side of the plate series page) when they're trying to match a photo they've taken with one on MPG. I did that for a long time too without realizing that a lot of species aren't represented by live specimens but are shown in spread specimens. Those plates aren't as easy to use but if you scroll through the pages using the buttons on the far left side of the page you will see a whole bunch more moths that you might not otherwise see. Good mothing. Parker _____ From: ncsc-moths-bounce@xxxxxxxxxxxxx [mailto:ncsc-moths-bounce@xxxxxxxxxxxxx] On Behalf Of J.

It was developed and published by Hodges back in 1983. Since that time a number of new species have been discovered and described. Instead of coming up with a new numbering system, the scientific community has decided to use decimals to add these new species, inserting them in the proper phylogenetic order as much as possible. In the case of Lithophane joannis, this species was described in the '90's and is believed to be closely related to L. petulca. Joannis is not well known, although it is not uncommon in places where it's food plant, buckeye (Aesculus) is common. In the case of MPG and Bugguide, no one has submitted a picture to them yet which is why it doesn't show up on the live plates (I guess I should send them a photo!). Species are continually being added to the Bugguide and MPG pages as folks contribute photos.

In doing that, Merrill has some species that I can't find on MPG, usually with a decimal and number after the Hodges number. My question is how to know these species/subspecies exist if they're not on MPG? The first pic below is the one that keyed me to this. On Merrill's page he has 9893.2 L. joannis. I can't find this on MPG or bugguide to compare pictures with mine to see if they match (it appears to match Merrill's fairly closely). Second, I'm attaching a picture that I have tentatively identified as Roland's Sallow, 10014 - Psaphida rolandi . Any other suggestons?
