What should I expect from a young mourning gecko during its first year?

Published October 29, 2026

The short answer

Expect a tiny, chirping, all-female gecko that may surprise you with eggs and miniature hatchlings during its very first year, because mourning geckos reproduce without males. Youngsters grow quickly on fruit-based diet and small insects, thrive in a planted vertical enclosure with high humidity, and do best in a small group where the pecking order settles early. Watch for eggs glued to leaves and cage corners from around the middle of that first year onward, and use KinsLe Care Teams to share the misting, feeding, and hatchling checks for your mourning gecko colony.

A young mourning gecko's first year contains a surprise no other common pet gecko offers: babies of its own. Mourning geckos are parthenogenetic, meaning every individual is female and females lay fertile eggs without ever meeting a male, producing daughters that are near-copies of themselves. A youngster bought as a thumb-length juvenile can be gluing pairs of round white eggs to leaves, bamboo tubes, and enclosure corners before her first year is out. Alongside that headline, expect a lively, social, whistling-and-chirping little lizard that is most active at dusk, patrols the glass for insects, and changes from pale and calm by day to darker and bolder at night.

Growing up in a colony

Mourning geckos are unusual among geckos for genuinely preferring company. Kept singly, a youngster often hides and feeds reluctantly; in a small group, the same gecko basks in the open, calls softly to the others, and eats with confidence. Groups do sort out a hierarchy, so you may see gentle head-bobbing, short chases, and the largest female claiming the warmest basking spot and the best egg-laying sites. That is normal colony politics as long as every gecko keeps weight on its tail and gets access to food. Because the geckos are escape artists of the highest order — a juvenile can slip through a gap that looks impossibly small — every cable port and door seam on the enclosure needs to be gecko-proof from day one.

A planted, humid, vertical home

These are rainforest canopy geckos, so height, foliage, and humidity shape the setup. A tall enclosure with cork tubes, bamboo hollows, and broad-leaved plants gives youngsters the hiding and egg-laying surfaces they seek out, while temperatures in the mid seventies to low eighties suit them better than hot basking lamps. Humidity should swing between a drier afternoon and a thoroughly misted evening, and that evening misting is also when the colony wakes, drinks droplets from leaves, and starts hunting. Ultraviolet light at low levels supports calcium use and natural behaviour, and it brings out the daytime activity that makes this species so watchable compared with strictly nocturnal geckos.

Fruit paste, tiny insects and calcium

Young mourning geckos eat two kinds of meals. A complete fruit-based gecko diet, offered fresh in a small dish raised off the floor a few times a week, supplies the base nutrition, and small live insects such as fruit flies and tiny crickets add the hunting stimulation youngsters clearly relish. Dust insects with calcium, and leave a small dish of plain calcium available, because egg production draws heavily on a young female's reserves even in her first year. Watch new hatchlings at feeding time in particular: a baby mourning gecko is barely longer than a paperclip, needs fruit flies rather than crickets it cannot tackle, and does best with food placed close to its favourite hiding tube.

Eggs, hatchlings and signs that need attention

Expect eggs to appear as hard, round, paired spheres glued firmly to a surface — never try to pry them off, because they are meant to hatch exactly where they were laid, and moving them usually destroys them. Incubation happens at room temperature inside the enclosure, and one morning you will simply find a miniature gecko, or its empty shell, announcing success. Seek a reptile veterinarian if a young female becomes lethargic with a swollen belly and stops eating, if tails in the colony grow thin while food is plentiful, or if a gecko develops soft, rubbery jaw or limb bones, since fast growth plus early egg-laying makes calcium problems the main health risk of this first year. Sharing the evening misting, diet changes, and new-hatchling checks through KinsLe Care Teams helps a mourning gecko colony thrive, because each completed task is timestamped for whoever checks the enclosure next.
