Members of Saturniidae, like Atlas Moth, Indian Moon Moth, even Ailanthus Silkmoth may attract more attention than many butterflies do.
The most well known local case to support not disclosing locality is the re-discovery of Freyeria putli in Sha Lo Wan in 2005 Oct.. Since then, dozens of photographers rush to the place. Days after, many plants have been trampled down. Lots of criticism appeared on the web saying that the locality of this butterfly should not have been disclosed. It is a very valid point to illustrate the bad effects of disclosing the locality of a rare species. However, very little have been mentioned about the positive side of disclosing this news: 1. Many people took the photos of this rare butterfly and have great funs. 2. Some lepidopterists found the larval food plant of this butterfly and completed the life history of this butterfly, that means we know more detail about it which can be very useful when we need to conserve it. 3. Solid evidence of the existence of this butterfly was established, one day when Sha Lo Wan is going to be developed, EIA report would certainly include them. As a whole, we gained more than we lost in this case.
Today, we all can easily take good photos of many rare butterflies because we know their locations and do not need to spend lots of time to search. Hasora vitta, Caprona alida, Ampittia virgata, Halpe paupera, Isoteinon lamprospilus, Chilasa agestor, Horaga onyx, Tajuria maculata, Pithecops corvus, Cethosia biblis... Why? Because we learn their locations and active timing from the web or other printed publications. 10 years ago, lepidopterists may spend years to look for them but only get very limited results. Bacombe (one of the most well known lepidopterists in HK) spent over 20 years on HK butterflies, he only recorded about 200 species. Today, most butterfly photographers spend only 1 -2 years to record 200 species.
At the time when we are harvesting the results of the generosity of previous generation, should we also consider to contribute ours?
We should respect everyone who do not like to disclose the locality when posting a photo record. At the same time, we should respect people disclosing the locality when posting a photo record on this forum and not to delete the information.
