Clapp waxay sii waday waxbarashadeeda qalin-jabinta dugsiga Louis Agassiz ee Anderson School of Natural History ee Penikese Island, Buzzard's Bay, MA sanadkii 1874. Waxay qaadatay hadalka Agassiz ee ah "Baro dabeecadda, ma ahan buugaag!" waxayna ku dabaqday waxbarashadeeda. Waxay ku soo bandhigtay aqoonteeda iyada oo loo marayo koorso embriyooloji ah oo ku taal Mount Holyoke, oo ay ku beddeleen tusaalooyin ka yimid ardayda dibedda. Iyada oo ay weheliyaan entomologists kale ee New England, Clapp waxay soo aruurisay cayayaanka ka yimid Buuraha White ee New Hampshire xagaagii 1875 iyo gobollada bartamaha-Atlantic ee 1877.
