Goldenrod Spider by Gowtham

Cathy Griffin of the Traverse Area Historical Society shared a little news from 120 years ago in 1905:

FRANK CARTER, local resident who had been in Chicago and Grand Rapids during the summer, returned Monday night being ill from the poisonous effects of a spider which walked over his arm, leaving a poisonous track at every step. Last week, while lying on the ground at Grand Rapids, an immense yellow spider jumped on his arm near his elbow and ran down to his wrist. Mr. Carter smashed his poisonous body on his arm and it immediately began to swell from the poison. The arm was inflamed and swollen with white spots. Under the advice of a physician, Mr. Carter went home to care for his arm.

It’s been a minute since I’ve featured a photo from Gowtham. He shares that while driving through the back roads of Huron Mountains from Houghton to Marquette, “I took a few wrong forks in succession and one of those forks had a plethora of Blue Vervains (the flower in the picture). Taking one wrong fork after another, driving slow and paying attention paid off – as one of those blue vervains had an uncommon yellow tinge. I stopped to look carefully and much to my surprise was this tiny little Golden Rod Spider.”

…These spiders may be yellow or white, depending on the flower in which they are hunting. Especially younger females, which may hunt on a variety of flowers such as daisies and sunflowers, may change color “at will”. Older females require large amounts of relatively large prey to produce the best possible clutch of eggs. They are therefore, in North America, most commonly found in goldenrod (Solidago sp.), a bright yellow flower which attracts large numbers of insects, especially in autumn. It is often very hard even for a searching human to recognize one of these spiders on a yellow flower.”

I want to be very clear that this spider is not venomous (and no spider has “venomous tracks”). Only the Northern Black Widow and the Brown Recluse have bites that endanger humans. The rest are out there happily dispatching harmful pests. My guess is that it was a Brown Recluse as their bites have sort of a bullseye pattern with a white center.
