A beautiful day to do some gardening. Unfortunately, I was constantly being distracted but butterflies and dragonflies.

While working, I flushed an unidentified Sulphur from my Senna plants which are just finally starting to come up. Fingers crossed!

Much too crowded. Park police were just coming in as we were leaving after we saw staff counting cars in all of the parking areas.
The highlight of the day was several Tawny Emperors munching away on Hackberry and three Giant Ichneumon Wasps with their ovipositors buried deep in a dead tree.

11 AM - 2 PM. Sunny, 70 degrees. Delightful breeze kept butterflies down. Little Wood Satyr count could easily have been many times higher; we covered only about 1/4 of the edge of one large field. Many Pearl Crescents heavily worn. The field along River Rd at River Road Park is getting overrun with mugwort although one patch of Bird's-foot trefoil/Crown vetch remains near the parking lot.

On our way back from birding various preserves earlier in the day, we made a brief stop late morning and walked through the grassland area. On our way back to the car, we found an Eight-spotted Forester in the path that I safely relocated to some honeysuckle where it nectared for a few seconds and then flew off.

A good amount of Wild Geranium flowering along wood edges. Sunlight patches of this attractive nectar source are always worth checking for grass skippers.

These once lovely limestone forests are now severely degraded with alien invasive plants chief among them Garlic Mustard, Japanese Barberry, and Autumn Olive. The fields, which are mowed annually, have patches of mugwort and, more recently, Chervil.

Yards Creek Pump Storage Facility, Blairstown Twp.
Warren County, NJ

10:00-2:00, full sun, 55-70º. This was our fourth consecutive annual May survey at this facility, most of which has been closed to the public since 9/11. (We are allowed to conduct butterfly surveys as volunteers to the NJ Endangered and Nongame species Program.) We survey in mid- to late May primarily for the very small population of Common Roadside-Skippers. This year a utility company had sprayed herbicide under power lines that cross a field that we survey annually. We also found that the Forest Service (presumably) had recently bulldozed and widened the fire-break trail at the upper reservoir where we find Roadside-Skippers. Seeing the damage, we were not optimistic, but a few hardy Roadsides did turn up to make our day.

For those who wish to access Yards Creek, check in at the guard station at the end of Walnut Valley Road and ask permission to access the Kaiser hiking trail near the old Boy Scout camp. You will be directed to a small parking lot near the camp. The facility is limiting this lot to 5 vehicles so it best to visit on a weekday. On weekends this lot fills up shortly after 8 when the guard station opens. The Kaiser Trail intersects the AT. By turning left (south) on the AT one may be able to find the sought-after Roadside-Skipper near the Raccoon Ridge hawk lookout. Check openings along the trail where Little Bluestem grass grows. The stretch of trail between the hawk lookout and the powerline to the south can be especially good. This area can also be reached by hiking the AT south from Camp Mohican Road in Blairstown.

In addition to the listed butterflies we saw a mother bear with 2 very small cubs, and 6 Bald Eagles. We also re-found 2 small Rhodora shrubs in the same location that we first discovered in 1999. Rhodora is an S1 species in NJ (very rare with no more than 5 known locations).
