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?

oops, now i have lost my image, will try and add. :confused:

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. :p

After that it is all plain sailing. :D
