Q- Does touching a butterfly's or a moth's wing hurt it?
A- No. Some scales may fall off, but it will not injure it. Lepidopterans lose scales every day.
Q-Is collecting bad?
A- Some people are vehemently against collecting. However, collecting responsibly is not bad. Insects reproduce at a tremendous rate. Collecting is not a cause of depletion. Still, it is not a good idea to collect tons of females and especially not isolated populations of endangered species.
Q-Can I obtain tropical lepidoptera/insects in the US?
A-Importing foreign insects violates the law. A PPQ permit is needed.
