[Odonata-l] Collecting was not the problems

[Bob Glotzhober]

I tried to e-mail a copy of this article from Journal Watch - but not
sure it made it - and if it did, I could not add a comment.

Here is the link for the article in Journal Watch about Europe's "Large
Blue Butterfly"

http://journalwatch.conservationmagazine.org/2009/06/17/save-a-species-1
01/ 

 

The key from my perspective is that years ago it was thought by local
workers that over-collecting was the cause of decline in the Large Blue
Butterfly. This article points out that conclusion was in error, and it
had to do with loss of ant species which in turn was due to decrease in
grazing by cattle. The lessons: Don't be too quick to judge cause and
effect; and, Another case where collecting was not a problem. 

 

Many people seem to be getting more and more negative on collecting
insects. I'm sure there may be some isolated cases where this can be a
problem, but again and again we see that insects that produce hundreds
or even thousands of eggs are not normally negatively affected by
collecting - but by habitat loss or change.
