Giraffe Stag Beetle(Prosopocoilus Giraffa Keisukei) Caresheet

Breeding:                                                                              

  • Ideal temperature: 71 F- 77 F

  • Amount of egg laid: 10-60 eggs

  • Laying bin: Like a majority of Lucanids, the Giraffa stag tends to lay in flake soil. Although the use of a breeding log is possible, this species reproduces effectively without the use of a breeding log.
    -Laying bin(no log):
    Step 1: Hydrate the flake soil. Hydrate to the point the flake soil can maintain a shape when you grip it tightly, but not too much to the point water drips when tightly gripped.
    Step 2: Press the bottom 70 percent of the flake soil firmly with a fist or the bottom of a glass jar
    Step 3: Gently lay the remaining 30 percent of the flake soil on top
    Step 4: Place jellies and husk chips/sticks in order to prevent the female from being unable to flip itself upright. (small note: I personally prefer to not use husk chips due to it spreading and getting mixed with the flake soi)
    Step 5: Place a mated female into the laying bin!
    Step 6: Retrieve the female from the laying bin in about 2-3 weeks
    Step 7: Retrieve eggs & larvae after waiting for about 2-3 more weeks!
    -Laying bin(with log):
    Step 1: Choose a wide and decently soft log(soft enough for your nails to make a mark). Possible logs to use include oak breeding logs, kawaratake breeding logs, or reishi breeding logs.
    Step 2: Scrape off the bark and yellow part of the log.(KEEP THE BARK!)
    Step 3: Soak the log in water(use weights to keep the log submerged!) for about 6 hours, then dry the log in the sun for about 2-3 hours.(SKIP IF USING REISHI OR KAWARATAKE LOGS!!!)
    Step 4: Hydrate the flake soil. Hydrate to the point the flake soil can maintain a shape when you grip it tightly, but not too much to the point water drips when tightly gripped.
    Step 5: Place a thin layer of flake soil on the bottom of the container
    Step 6: Place the log on top, then cover 2/3 of the log using flake soil, press the flake soil firmly
    Step 7: Place jellies and husk chips/sticks in order to prevent the female from being unable to flip itself upright. In this case the bark you peeled off in the beginning works good.
    Step 8: Retrieve the female from the laying bin in about 2-3 weeks
    Step 9: Retrieve eggs & larvae after waiting for about 2-3 more weeks!

    Notes:
    -Mating/laying would decrease life expectancy

    -The hatching rate will decrease as the parents age.

    -Male can kill females during mating with their large mandibles. Bind the males mandibles in order to prevent death in females.

Larvae:                                                           

  • Egg period: 20-30 days

  • Larval period: 7-13 month

    Notes:
    -The larger the giraffe stag beetle the longer the larval period.

    -Raising the larvae in kinshi can speed up the growth and lead to larger adults.
    -Higher the temp the faster the larvae matures

  • Larvae food source: Kinshi or flake soil

  • Pupa period: 1 month

  • Dormancy period: 1-3 months
    Notes:
    -The higher the temperature the shorter the dormancy period

Adults:                                                              

Adult lifespan: 8-10 months

Size: 50mm-122.0mm

Notes:
-There are 9 known subspecies of Prosopocoilus giraffa, the largest subspecies Prosopocoilus giraffa keisuke is the biggest amongst the 9 subspecies and also the longest stag beetle in the world! A few other subspecies include Prosopocoilus giraffa daisuke, Prosopocoilus giraffa giraffa, Prosopocoilus giraffa timorensis, etc.
