Lines of Evidence
The modern study of butterfly higher classification began with Ehrlich's phenetic use of hundreds of previously overlooked morphological characters in tabular form, across families and major groups (Ehrlich, 1958). Scoble (1995) and others continued the search for new characters, but with their application to cladism. Larval characters are now commonly integrated with those from adult butterflies. The addition of molecular data has allowed researchers to resolve clades in many lineages.
Evidence is gleaned from paleontology where some 50 butterfly fossils have been identified, from morphology and the study of homologies, from molecular genetics and comparative biochemistry, from comparative ethology, and from present-day geographical distributions and ecology. Even though butterflies are among the most studied insects, new findings are coming to light almost every month, and the prospect of a stable butterfly classification based on strongly supported clades is seemingly within reach.

“Called as partners in Christ’s service,
Called to ministries of grace,
We respond with deep commitment
Fresh new lines of faith to trace.
May we learn the art of sharing,
Side by side and friend with friend,
Equal partners in our caring
To fulfill God’s chosen end.”
—Jane Parker Huber (b. 1926)
“Who will in fairest book of Nature know
How virtue may best lodged in beauty be,
Let him but learn of love to read in thee,
Stella, those fair lines which true goodness show.
There shall he find all vices’ overthrow,
Not by rude force, but sweetest sovereignty
Of reason,”
—Sir Philip Sidney (1554–1586)
“You don’t decide to build a church because you have money in the bank. You build because God says this is what I should do. Faith is the supplier of things hoped for and the evidence of things not seen.”
—Jim Bakker (b. 1940)
