The Grasshoppers of Bridge Park

by Eric Neubauer

I’m one of the members of our Chapter who’s visiting various city parks in Milam County on Tuesdays. Here’s what I found at Bridge Park in Rockdale, which is an area full of some of the famous bridges of Milam County. I was hoping to add to my goal of documenting all the grasshoppers in the county.

As I expected, the very first grasshopper I picked up was one I’d hoped to run across for a long time. I knew instantly what it was, but somehow expected it to be larger.

Regarding the Aztec grasshopper, it was only about a ¼” long and pretty lively. I got three photos and it was gone. Looking at other images at iNat suggests it’s a tiny grasshopper and overlooked for that reason. I can’t find anything about sizes on the internet. I was looking through the fallen leaves behind the calaboose at Bridge Park.

Then there was a peculiar looking nymph I never saw before. I didn’t necessarily think it was a species I hadn’t seen. This was correct, but it was the first time I’d encountered a nymph. I think I identified it correctly.

In looking at the satellite views at google maps, I realized that an abandoned railroad once ran through Sumuel Park, one of the other parks we visited. It was the one that came up though Deanville and continued on through Cameron.

This was a great visit, definitely another case of the Linda Jo’s time-to-get-off our-butts initiative. There are several sites I’ll be sure to visit again on a regular basis.

How I’m Doing on My Grasshopper Quest

I’ve seen 27 Acrididae species in Milam County. There are a total of 31 observed. Of the four I don’t have, two observations are bogus (wishful thinking applied to nymphs), one is Schistocerca lineata, which I’ve seen in Burleson County, and the other is Melanoplus punctulatus which Sue Ann has seen. Since the common name is Pine-tree Spur-throat grasshopper, I think I need to go somewhere there are pine trees.
