7 things to know before welcoming a Didier's Stag Beetle

1Mandible shape varies by individual
Mandible shape and size vary noticeably between individual males, and larval-stage care can influence the final result. If you're drawn to a particular mandible shape, pay attention to rearing conditions during the larval stage.
2Temperature control is key
This species is sensitive to heat, so keeping the environment cool during summer is important for longevity. Keep the enclosure out of direct sunlight and away from rooms that get too warm.
3Adult activity period is limited
Adults typically live for six months to a year. Beetles often enter a dormant period right after emerging, so don't worry if yours isn't active right away.
4Don't house males together
Males fight using their mandibles, so keeping multiple beetles means housing them in separate enclosures. Unless you're aiming to breed them, it's also safer to keep males and females apart.
5Prepare substrate and anti-tip materials
Use insect substrate or leaf mold as bedding, and add climbing branches or bark so the beetle can right itself if it flips over. Mist occasionally to keep humidity from dropping too low.
6Keep insect jelly stocked
Insect jelly is the main food source and should always be kept fresh and available. Running out of food for an extended time can quickly weaken the beetle.
7Prepare with intermediate care in mind
Care level is considered intermediate, so first-time keepers should review basic beetle-keeping basics beforehand. Set up the enclosure and temperature control before bringing one home.
