Sinlahekin Summer 2012: parade of butterflies

Now that I've built up a butterfly collection for the Sinlahekin and myself, I have been adding to my camera equipment and focusing more on photographing the butterflies I see and only collecting butterflies for new records, new locations, or to fill in other gaps in the collections. It's difficult juggling a large camera with a heavy macro lens, external flash, a small notebook, pen, butterfly net, forceps (flat-tipped tweezers for handling butterflies), and assorted other gear! So, sometimes I choose one over the other, and therefore may miss photographing a new species because I only have my net, or I miss collecting an important specimen because I only have my camera. I was quite satisfied with my recent trip to the Sinlahekin though, because I only missed photographing a few of the species on my list, and I was able to collect several important specimens for the collection. I plan to spread (pin, mount, and dry) those specimens later today, and will post photos of them once they are dry in a few days.

Below is an assortment of some of my favorite photos of live butterflies from my trip. I have a new program (Adobe Lightroom) that I've been using to add copyright watermarks to my photos. I noticed that it tends to make the whole picture a little more grainy (particularly in the Behr's Hairstreak photos), even when I turn off the options to convert the photo to different resolutions. I hope it isn't too distracting, but I've been noticing my photos popping up in Google searches for these species, so I wanted to make sure they aren't being copied elsewhere without credit. Please bear with me as I learn how to process all my photos!

Anicia Checkerspot Euphydryas anicia - I set my butterfly net aside while photographing dozens of mudpuddling butterflies, and when I turned around, this little guy was sipping up my sweat on the net handle, not to mention it's bright red like a flower!

Satyr Anglewing Polygonia satyrus, this one was so interested in the weatherstripping on my car door that it flew into my car twice after I shut the door!

Chryxus Arctic Oeneis chryxus, male

Mourning Cloak Nymphalis antiopa, normally these have a yellow border, but they overwinter as adults so this one is quite faded and tattered!

Sinlahekin Wildlife

In addition to 88 species of butterflies, the Sinlahekin Wildlife Area is also home to many other animals. Some are quite common and often seen, such as whitetail deer, while others are infrequent visitors, such as moose. While the signs posted at each entrance seem to give a lot of rules, they are intended to preserve the beauty of the wildlife area for subsequent visitors, and protect habitat for its huge diversity of plants and animals. The Sinlahekin is home to some of the rarest plant species in Washington, not to mention over 40% of the butterfly species in Washington can be found in this 14,300 acre hotspot!

This bullsnake wasn't very happy about me waving my butterfly net at him to get him to move off the road, he reared his head and hissed at me the whole way, but he obeyed! These and rattlesnakes are frequently killed on the main road through the Sinlahekin, some by accident, some on purpose.

The lambs got nervous at me watching them, so started to wander over to the adults, one started nursing.

Five lambs and nine adults, one adult (left) has a radio collar.

3 = species seen July 2
8 = species not seen in June before on the Sinlahekin
1 = species not seen in July before on the Sinlahekin
1 = new record for the Sinlahekin: Sonoran Skipper (Polites sonora)
2 = species seen every day: Blue Copper (L. heteronea) and Boisduval's Blue (P. icarioides)
10 = species seen only once: Northern Cloudywing (T. pylades), Sonoran Skipper (P. sonora), Behr's Hairstreak (S. behrii), Echo Blue (C. echo), Greenish Blue (P. saepiolus), Arctic Blue (P. glandon), Callippe Fritillary (A. callippe), Hydaspe Fritillary (A. hydaspe), Green Anglewing (P. faunus), Dark Wood Nymph (C. oetus).

I found dozens of Purplish Copper eggs all over this plant near Fish Lake, the first time I've seen the eggs or larvae of this species. I'm waiting to have the plant identified, it wasn't in bloom at the time which makes it difficult.

I hiked to where we found the Northern Cloudywing colony last year, and found several more eggs, and am also waiting for a positive ID on these (apparently two) species.

On the last day of my trip (morning of July 2) I spent some time searching for eggs and larvae of Boisduval's Blues (Plebejus icarioides) on lupine in an area that had been burned (controlled) early this year. The lupine was blooming profusely and I found several eggs and one adult female. In another location further south, I found a few more eggs and one larva.

Northern Cloudywings: follow-up from last year

I'm busy preparing for another trip to the Sinlahekin Wildlife Area (almost 4 whole days!), but I wanted to put up a quick post before I leave in a couple days. Do you remember all my talk about cloudywings last year, after my trip to Oklahoma, and then confirming Thorybes pylades at the Sinlahekin? I won't bore you with more excited chatter about this little gem (although you may hear more if I can find any larvae on this trip!), but here are photos of the three specimens I collected at the Sinlahekin last year. I'm sure two are females, and almost positive that the other one is a male. Male Northern Cloudywings (Thorybes pylades) have an obvious stigma (see my butterfly terminology post) on the leading edge of their FW, which makes the wing look slightly angular. Normally the stigma is much lighter than the rest of their dark wings, but it is less obvious in faded individuals, such as these. I'm open to corrections if anyone reading this is more familiar with cloudywings.
