Temperature & Humidity

Keep the insects at 22-27 °C and 60-80 % humidity. Mist the food plant with lukewarm water every two or three days to raise the humidity. Rearing at lower, room-level temperatures yields a higher proportion of males at hatching.

Breeding & Egg-laying

Parthenogenesis plays essentially no part, so both sexes are needed. Adult males live up to four months, exceptionally long for Phyllium, and during mating they ride on the female's back for days at a time. The eggs are about 5 mm long, just under 3 mm wide and 10 mg in weight, and hatch after four to five months. Because the males are long-lived, fertilised eggs are easy to obtain, hatch rates are higher and the nymphs are more robust.

Cohabitation

They are leaf feeders and do not attack one another, so a group can share one enclosure. Adult males are active at night, walking and flying through the branches in search of a female. Because a handled insect will shed its legs, move the animals on a leaf or twig rather than picking them up.

Lifespan & Rearing Period

Eggs hatch after four to five months and the nymphs need a further four to five months to mature, males slightly faster. Adult males live about three months and females usually six to nine, exceptionally up to a year. From the second moult the sexes can be told apart by the abdomen, which narrows into a diamond shape in males and broadens in females.

Health & Notes

The culture was first circulated as Phyllium spec. (Philippines) or, incorrectly, as Phyllium siccifolium, and the old names still appear on photographs and labels. Foreign phasmids count as quarantine pests under Japan's Plant Protection Act and live specimens may not be imported except with ministerial permission, so choose animals bred within Japan. They must never be released or abandoned outdoors.

About Philippine Leaf Insect

A leaf-mimicking insect native to Luzon, Philippines. Females reach 65–98mm and closely resemble a leaf, while males are slimmer at 55–68mm and capable of short flights. Considered a beginner-friendly species to keep.

7 things to know before welcoming a Philippine Leaf Insect

1. 1Enclosure & Ventilation

   This species thrives in warm, humid conditions, so a well-ventilated enclosure misted regularly works best. If it gets too dry, molting can go wrong, so consistent misting is important.

2. 2Keeping Food Plants Fresh

   They favor leaves from the rose family, such as bramble, so a steady supply of fresh leaves is essential. Keeping the cut stems in water helps the leaves stay fresh longer.

3. 3Male vs. Female Differences

   Females are larger at 65–98mm, sturdily built, and unable to fly, while males are slimmer at 55–68mm and capable of short flights. Comparing these differences is part of the fun of keeping this species.

4. 4A Calm Temperament

   These insects move very slowly, show no aggression, and spend long stretches motionless while mimicking a leaf. They aren't suited to keepers wanting an active pet, but are ideal for quiet observation.

5. 5Timing Around Molting

   During the nymph stage, they molt several times as they grow, and their bodies are extremely delicate during this process. Avoid startling or handling them during or right after a molt.

6. 6Typical Adult Lifespan

   Adult females typically live around 6–9 months, with some individuals reaching close to a year. Adult males have a shorter lifespan, typically around 3 months.

7. 7Ease of Breeding

   This is considered one of the easier leaf insect species to breed. Combined with its beginner-friendly care level, it's an approachable species even for those new to keeping insects.
