Lined earwig

Lined earwig

Doru taeniatum

A species of Doru

The lined earwig (Doru taeniatum) has earned its name from the lines that you see leading horizontally across its body. The species flies fairly easily compared to some earwigs. In the presence of light when in tropical locations, these insects do have the capacity to swarm in the thousands. Disgustingly, they can also shoot jets of foul-smelling yellow liquid to deter would-be predators.

Life Cycle of Lined earwig
Egg The eggs of lined earwig are often deposited in clusters in the soil. They are oval, white, and will change slightly in color as they mature. There is no distinct transformation in shape or size during this stage.
Nymph After hatching, the nymphs resemble miniature adults, but lack wings and reproductive structures. With each molt, they increase in size, gradually develop wing buds, and their coloration may vary as they progress through successive instars.
Adult Emerging as adults, lined earwig exhibit fully developed wings and reproductive organs. The body becomes harder and darker. Adults are responsible for dispersing and breeding, ensuring the continuation of the species.

Habitat Preferences of Lined earwig Through Different Life Stages
The eggs of lined earwig are typically hidden in the soil or under debris to protect them from predators. Nymphs, resembling miniature adults, grow in similar habitats, benefiting from the moisture and organic matter present. To spot nymphs, one might investigate under stones or inside rotting wood. As they mature, these insects continue to favor damp, dark environments such as gardens, fields, and even inside homes occasionally, where they can be found under kitchen sinks or in basements. To find adult lined earwig, searching at night when they are most active, especially near lights or in vegetation, would be most productive.

How and Where Can You Find Lined earwig at Different Life Stages
Nymph Lined earwig nymphs can often be found in moist environments such as under logs, rocks, or leaf litter. To find them, carefully lift potential hiding spots and look for small, wingless versions of the adults.
Sub-adult lined earwig are larger than nymphs but still lack fully developed wings. Search for them on plants or in crevices in walls and bark at dusk when they are more likely to be foraging.
Adult Lined earwig adults can be located by scoping out the areas around outdoor lights at night, where they may be attracted to the light source. Alternatively, you can inspect the same moist hiding places as with the nymphs and sub-adults during the day.
