What Francis Walker described in 1863 as Notoreas perornata was probably found somewhere in inland Hawkes Bay or Taupo where Colenso regularly travelled as part of his parish. Colenso (1811-1899) was an interesting and at times controversial character who among many notable achievements, wrote about the signing of the Treaty of Waitangi from first- hand experience. He was the first European to discover moa bones and research their significance. He also made impressive collections of plants and described many new species, collected insects and was the first person to collect boulder copper butterflies. He served in local and central government and corresponded with a great many international scientists. In total he published 104 articles in the Transactions of the NZ Institute on diverse subjects in natural history and culture. What’s in a name? Notoreas moths belong to the large family Geometridae which is NZ’s most diverse. The name Notoreas, a word of Greek derivation, alludes to their southern hemisphere distribution. There are at least 30 species of them, all endemic to NZ - the number is Notoreas casanova on Tiwai Spit, Southland, amongst its larval approximate as more have been hostplant Pimelea lyallii, also confined to this section of coastline. discovered in recent times.
