Thanks Evra, That would be nice to collect those, but the Sierra Nevada is a vast range, and there are so many spots to collect. Now, if those hepialids are found in the one meadow yes, one meadow now, then that would be like looking for a needle in a haystack. The cool thing is that I have a lot of ground to cover since the Sierras are just in my backyard, at least the east slope/Carson Range and Tahoe is. I would only wonder if there are any of these moths in the Great Basin ranges like the Toiyabes, Monitor, Toquima, Ruby, and Schell Creek ranges.

Luck and hard work are the ingredients needed for US Hepialidae. I've managed to collect Sthenopis argenteomaculatus, S. purpurascens, S. auratus, Gazoryctra hyperboreus, G. pulcher, G. wielgusi, G. lembertii, Korscheltellus gracilis, Phymatopus hectoides and Phymatopus californicus.
The best night was collecting G. wielgusi in the white mts of Arizona - warm, humid, just after a mid-day storm. Between 8 traps and a mercury vapor light I got 7 moths. All of those flew within an 11 minute window: 7:47-7:58. Cool weather and rain seem to be killers, "cool" being nearly unbearably cold for a summer rain storm in the mountains.

Just ran across these figures from the 2010 "Annotated List of the Lepidoptera of Alberta, CANADA" by G. Pohl, G. Anweiler, B. Schmidt & N. Kondla. There are approximately 500 worldwide spp. of Hepialids found mostly in the tropics & Australia. N. Am. has a grand total of only 19 spp. Certainly explains why many (particularily the small spp.) of the N. Am. fauna are rarely observed or collected.

This is the best web page on Hepialidae boghaunter - I found it very useful - all known genera are listed + papers you can download. www.johngrehan.net/index.php/hepialidae/ |
