PowerHobo 0 Report post Posted August 30, 2018 I may be somewhat unexpectedly receiving some cactus longhorn beetles very soon, and am just curious if anyone has any experience with the best substrate for them. I want them to be able to breed if they choose, though I'm not counting on it. Since they eat and breed near prickly pear and cholla, I assume their preferred sub is similar to the planting needs for those cacti (1:1 potting soil and sand)? I appreciate any helpful knowledge in advance! Share this post Link to post Share on other sites
arizonablue 0 Report post Posted August 30, 2018 I have three, and I'm keeping them on a mix of coir and sand, mostly sand. Mine have mated but I have not seen any eggs deposited. In addition to cactus, they will eat beetle jellies. They also like to climb a lot, mine spend most of their time perched at the top of a piece of cholla.
