Why Breed Death's-Head Hawkmoths?
Acherontia atropos is one of the most famous moths in the world, known for the skull-like marking on their thorax and their starring role in "Silence of the Lambs." But beyond their spooky reputation, these are actually perfect moths for beginners.
What Makes Them Special
- Hardy & forgiving - mistakes rarely cause major problems
- Fast development - complete lifecycle in just 2 months
- Large & impressive - caterpillars grow to 10-14cm long
- Unique behavior - adults steal honey from beehives and can squeak loudly
- Beautiful variations - caterpillars come in yellow, green, and rare brown forms
Difficulty Rating: 4/10 - Ideal for Beginners!
Eggs
Small, pale yellow eggs hatch in 5-10 days depending on temperature. Keep them in small containers or Petri dishes at room temperature. No need for spraying with water. Open daily for a few seconds to allow air exchange.
L1 Caterpillars (First Week)
L1 refers to the first instar, which is the earliest stage of a caterpillar's life immediately after hatching from the egg and before its first molt. Most butterfly and moth species typically progress through five instars (L1 to L5) before they are ready to pupate, although some species can reach L6 or L7 depending on environmental factors like temperature and food availability.
Tiny yellow hatchlings that turn green after feeding. Keep them in small plastic containers with fresh host plant leaves. Make sure the containers stay closed to keep the food plant fresh and prevent drying out. Open the container once a day to remove droppings and allow fresh air to circulate. They tend to wander a lot before settling down to eat.
Pro tip: Handle freshly hatched caterpillars with a soft brush. This allows you to gently pick them up and transfer them into your plastic container without causing injury. A brush can also be used for older caterpillars.
Best Food Plants:
- Ligustrum (privet) - stays fresh longest, available year-round, grows everywhere!
- Tomato leaves - easy to find, excellent growth
- Potato leaves - readily available
L2-L3 Caterpillars (Weeks 2-3)
Beautiful colored patterns start developing. Move them to larger containers or mesh cages at this stage. They eat much more now, so change the food every 2-3 days and keep the enclosure clean. If using a mesh cage, place the food plant stems in a bottle with water to keep them fresh, but make sure the caterpillars cannot reach the water - plug the bottle opening with cotton or a piece of paper towel to prevent drowning.
Key Points:
- Good airflow essential (prevents disease)
- Remove old food and droppings regularly
- Temperature: 22-28°C works best but room temperature is just fine as well :)
L4-L5 Caterpillars (Final 2-3 Weeks)
These become giants! They need large mesh cages and eat enormous amounts daily. L5 caterpillars can reach 10-14cm long and are very impressive.
Housing: Large mesh cages (minimum 30x60cm)
Feeding: Daily fresh food changes - they're eating machines!
Pre-pupation signs: Orange markings appear on their back when ready to pupate, and the caterpillar starts to wander around the floor of the cage/box.
Important:
- Never spray with water (they like dry conditions)
- Clean out droppings daily
- Always have abundant fresh food available
Pupation
When caterpillars develop orange markings and start wandering frantically, they are ready to pupate. Move them immediately to individual pupation containers. Place each caterpillar into its container, close the lid securely, and let it do its thing without disturbance.
Setup:
- Individual small boxes (one caterpillar each) - small plastic containers, like the ones used for food salads from grocery stores, work perfectly
- Fill with moist soil, wood chips, or vermiculite
- Keep in a dark place
- Secure lids with ventilation holes - they will try to escape!
- Once the caterpillar burrows, open the lid after a few days
Timeline:
- They burrow and pupate within a few days
- It is best to keep the caterpillars in plastic containers
- If needed, wait 1–2 weeks before carefully digging up the pupae
- Handle gently - fresh pupae are soft
Pupae
Pupae start wine-red and gradually darken to brown/black as the moth develops inside. They take 3-4 weeks to emerge.
Care:
- Keep at 24-26°C for best results, but room temperature is just fine :)
- Ideally, keep the pupae inside the same plastic box they pupated in - simply open the lid and let the moth emerge on its own
- Make sure the substrate level is about 2-3 cm below the rim of the box so the moth can crawl up the plastic wall after emerging
- Place the open box inside a mesh cage, allowing the moth to climb higher and properly expand and dry its wings
- Place on tissue paper in cages if needed
- Light misting before emergence helps
- Don't keep them cold long-term - it damages their health
Adult Moths
Adult Death's-Head Hawkmoths can live up to 2 months and are fascinating creatures with their skull marking and squeaking sounds.
Feeding Adults
Unlike most moths, these feed on honey, not nectar.
Honey-water solution: Mix 50% honey + 50% water.
How to feed:
- Wait 2-3 days after emergence to start feeding
- Gently hold the moth and extend the proboscis with a toothpick
- Place the proboscis in a honey solution
- Feed every 2-3 days
- I personally like to use a syringe for feeding - it works very well if you have someone helping you. One person holds the syringe with the honey solution while you carefully unroll the proboscis with a toothpick and place it inside the syringe tip
- The moth may struggle a lot, but don't be afraid to use a bit of force to hold it securely - these are robust moths and you will not hurt them when handled properly
- Over time, they will learn the routine and cooperate more
Breeding
- Males: Ready to breed at 5-7 days old
- Females: Can breed immediately but best when well-fed
- Pairing: Happens at night in a dark, well-ventilated space
- Eggs: Well-fed females lay 150+ eggs over several weeks
- It is best to place some fresh food plant inside the cage with the females - this helps stimulate egg laying, and they will lay eggs both on the leaves and on the sides of the breeding cage
Breeding Setup:
- Room temperature (20-22°C minimum)
- Complete darkness at night
- Gentle airflow helps stimulate pairing
- Don't disturb them during nighttime hours
Best Host Plants
Top 3 Choices for Success:
- Ligustrum (Privet) - Evergreen, stays fresh for a long time, available year-round, and commonly found everywhere as a live hedge
- Tomato plants - Easy to find, excellent growth results
- Potato leaves - Readily available, caterpillars love them
These three will cover all your breeding needs. Always use pesticide-free plants!
Basic Environmental Needs
Temperature: 21-28°C throughout lifecycle (room temperature minimum for adults)
Humidity: Moderate - never spray caterpillars directly
Ventilation: Essential for preventing disease - use mesh cages from L3 onwards
Common Problems & Solutions
Caterpillars dying: Ensure fresh, pesticide-free food and good ventilation.
Slow growth: Increase temperature to 24-28°C.
Failed pupation: Use individual containers with proper substrate.
Adults won't feed: Be patient with hand-feeding, try fresh honey solution.
No breeding: Make sure both sexes are well-fed and provide darkness at night.
