Among the documents Nigel Buckley sent in 1984, you find his notes and illustrations.
“What can we gleam from the few sightings we have documented of these creatures? They clearly appear to be related to insects, only at a much larger scale.”
“Are they part of the same species, or perhaps a broader genus or family? Provisionally, I have decided to treat them as a single genus, which I call Megalomorpha.”
“I cannot say if the myriad forms we see are due to extreme individual variability or if several species exist.”
“What makes me lean towards the single-species variability hypothesis is the exuvia (shell) found in Maine.
“These moults are more common in insects going through partial metamorphosis, which suggests Megalomorphae may be capable of radical changes in form later in life.”
Nigel had spent all his life studying these insects since he reportedly found one in Tanganyika in 1923.
He passed away in 1986, not being able to complete his life work of redeeming his image in the scientific community.
Most of the evidence you have seen so far is his work.
