Quick trip to look for some invasives. Found Opuntia tomentosa and Harrisia tortuosa.

Opuntia tomentosa and Opuntia stricta are both very abundant here, but fortunately the Harrisia are still an hour or so away. Their growth form reminds me of Stenocereus eruca. I stood in a patch of dead thorns and gee did they go straight through the shoes. Lesson learned, be more observant. To be honest it just looked like a patch of dead grasses.

Anyway, pics!

This next picture is the clump of dead spines I was talking about.

Do you seed any cactus insect (Cactoblastis cactorum) around that opuntia?

On these particular plants I didn’t note any, but they tend to be mainly in areas with larger population density.

Thought I had some pics but must not have taken anyz
