A Warm Kind of Cold

Last week, I complained about the long brown winter we’ve had, and wondered when spring was coming.  Well, it’s still brown – we missed out completely on the last snow, which had been forecast to give us up to four inches of photographic beauty.

On the upside, I went out to my favorite wetland yesterday, and while it was only 16 degrees F, it actually felt much warmer than that.  A lack of wind helped, as did periodic sunshine, but the air just felt like it was warming.  It’s an odd thing, isn’t it?  The unemotional thermometer said 16 degrees, but  I think my knowledge that the temperature was going to get above freezing later in the day (it did!) helped warm me up.

There were other signs of impending spring.  Red-winged blackbird males have returned to begin setting up and defending their territories. (Females, the smarter ones, are apparently content to wait a few more weeks until it warms up and the boys have fought their silly little battles.)  Sandhill cranes are starting to fill the sky as the annual migratory phenomenon begins again here on the Central Platte River.  I’m still waiting for the first song sparrow to begin singing, and I’m guessing it’ll be a while until I see the first bees emerging, but things are looking up.

Here’s a photograph from my short hike yesterday.  I’ll share more later this week.

Photo of the Week – February 20, 2014

This the time of year when I start getting antsy to see green vegetation, flowers, and insects again.  Since our prairies are still brown and dormant, I have to live through photographs from previous field seasons.  Here is a photo from August 2012 I found yesterday while looking through old images.

Bush katydid (Scudderia?) on a rosinweed (Silphium integrifolium) flower – The Nature Conservancy’s Platte River Prairies, Nebraska.

The beautiful green creature in this image is a katydid, not a grasshopper.  The easiest way to tell is by looking at the length of the antennae, which are very long on katydids but very short on grasshoppers.  There are numerous species of both katydids and grasshoppers in our prairies, and by late summer, most have gone through their final molt and have become fully adult – with the wings to prove it.

You may not be aware that katydids have special hearing devices on their legs.  In the photo above, you can see dark pits in the “forearms” of the insect, right below their “elbows”.  Inside those pits are tympana that vibrate just as our own eardrums do.  For an excellent description of this, and an explanation of how it’s an advantage to the katydid to have its ears on its legs, read this post on the Living with Insects Blog.
