Charles Edwin Clarke (1885-1952) was an amateur entomologist in New Zealand during early to mid-1900s. He had an enormous fascination for Lepidoptera (butterflies and moths) and Coleoptera (beetles). He was a dentist by profession, but like many natural scientists of this time, his entomology work was merely a hobby. An impressive hobby at that, especially for Clarke, who published papers on Lepidoptera and discovered new species in his ‘spare’ time.
Tāmaki Paenga Hira Auckland War Memorial Museum has over 5,500 specimens from Charles Clarke, both in our exotic and New Zealand collections. However, this large collection is still being databased to this day. He collected many types of insects from all over New Zealand, Rarotonga, and Queensland.
Charles Clarke was a notable collector; some might say he had an obsession for collecting insects even collecting on Christmas day. His first true love appeared to be that of insects, the hot summer weather would have made it ideal for such bug hunting adventures (…but perhaps may have contributed to him having had multiple marriages).
Over 200 of Clarke specimens within our records were collected on Christmas day, from numerous sites between 1911 to 1946. He collected most of his Christmas specimens around New Zealand (Figure 2). However, also collected from Wentworth, Australia in 1930 and Arorangi, Rarotonga in 1937 on Christmas day.

This map shows the locations where insects were collected by Clarke on Christmas day from around New Zealand. Including the locality of the following specimens: Mimopeus clarkei (AMNZ13708), Holcaspis angustula (AMNZ89466), and Capua semiferana (AMNZ213708)
During his life he discovered and described a few species of moths including Ericodesma cuneata, Heterocrossa sanctimonea, and Asterivora urbana all of which the holotypes (the specimen used to formally describe the species) are kept at Auckland Museum.
While Clarke was still alive in 1929, he donated his vast collection of New Zealand insects and cabinets to Auckland Museum. In 1952 Clarke died, his second collection of beetles was acquired in 1955-1956 by both Auckland Museum and the British Museum. The collection was large and distributed evenly between the two museums. Many of the species he collected and then donated to the Museum were also studied by the entomologist Alfred Philpot who described new moth species from his collection.
If you have time at all this Christmas, think like Charles E. Clarke and spare a moment to look for some insects running, buzzing, or flying around on this hopefully sunny Christmas day.
