Monday macrobug: Orange wasp
Saw this one on the Neoacadian Inner Piedmont field trip before GSA in the fall… I guess it’s something of a break from tradition to show you a bug from any place other than my yard, but this one’s pretty enough to justify the excursion… Yes, that’s the Walker Top Granite that it’s resting on.

Friday fold: Up on Opequon Creek
I got a call last month from Rebekah Wiedower, a landowner up in Frederick & Clarke counties (her family’s property includes pieces of both), inviting me to come up and look at some anticlines and synclines that Dan Doctor (USGS) had identified on the bank of Opequon Creek.

Monday macrobug: Katydid
Happy New Year’s Eve! Here’s a katydid seen on my porch back before it got really cold: Can you tell if it’s a male or a female? (Hint: look for the ovipositor!) This one’s out of focus, but I like it anyhow because of the character lurking in the background: Happy New Year!
