Stuck again

[2manynames]

I have solved this puzzle by using one option of two and then repeatedly resolving until I got there. This is the end of where I cannot logically exclude more. Any pointers?

You can eliminate a few more combinations by using clues 2, 4, and 1.

From clue 2, we see that $1220 cannot be Red Admiral. Therefore, Lowell can never be Red Admiral.

Then from clue 4, since Red Admiral can no longer be Lowell, then $1200 cannot be Lowell either.

Now from clue 1, we know that Lowell has to be $10 less than Joel. At this point Lowell can only be $1210 or $1220, and Joel can only be $1220 or $1230.

Either Joel or Lowell has to be $1220.

That means that Trevor cannot be $1220.

Use clue 9 to put the Megathymidae in the $1220 slot. That forces the Adonis Blue up to the $1190 slot.

The rest of it cascades from there.

Hope that was right!

Thanks so much, that is the way forward. To solve it I had used either solution to clue 2, and discovered that it only worked if Lowell was Satyrid, but I knew that this was not the way forward.

I have had to re read your clues a number of times but finally get that Lowell cannot be 1200 cause he can't be red admiral, because Kelly has to fit there too.

After that it is all plain sailing.
