hides inside the flower heads tightly
- Size
- Length: 1–2 mm
- Lifespan
- 1–2 years
- Diet
- Most species feed on plant sap using piercing-sucking mouthparts. Some are predatory feeding on mites.
- Habitat
- Inside flower heads, on undersides of leaves and in the air during humid weather. The fringe-winged residents of the petal.
- Range
- Throughout North and South Islands in gardens, crops, forests and grasslands. Most common in lowland areas with diverse plants for feeding. Present in almost every terrestrial habitat with vegetation.
- Endemism
- Endemic
- Main Threats
- None significant. This group is widespread and common. Some species are considered agricultural pests but controlled using integrated pest management. Faces no conservation threats.
- Population
- Commonly called thunderflies because they often swarm just before a summer storm. Some of the smallest winged insects in New Zealand.
- Conservation Status
- Not Threatened
- Human Risk
- caution
- Handling Note
- tiny insect, piercing mouthparts cause minor skin irritation
- Conservation Note
- Endemic insect; not assessed by NZTCS as invertebrates are generally outside the scope of current threat classifications.
- Te Ao Māori
- Thrips have no recorded Māori name. They represent the principle of atmospheric connection and serve as a symbol of the power of the swarm within the natural heritage of New Zealand. Known as the storm-bringers or thunderflies they occupy a cultural niche as a tiny reminder of the link between the smallest insect and the largest weather pattern. The air around us is alive and reactive and the most subtle shift in the wind is felt by a myriad of invisible travelers.
Often appearing as nothing more than tiny black specks within the heart of a daisy or rose. Thrips are the specialised pollen-dwellers of the New Zealand garden defined by an anatomy that defies conventional insect flight. These minute slender insects typically measuring less than 2 millimetres possess unique fringe-like wings that resemble miniature feathers rather than solid membranes.
Because of their diminutive size and the high viscosity of air at their scale they do not fly in the traditional sense. Instead they swim through the atmosphere using their delicate fringes to catch the breeze and navigate the aerial currents. This microscopic journey allows them to travel vast distances often appearing in massive drifting clouds when the humidity rises and the barometric pressure shifts before a summer rain.
As micro-pollinators thrips play a vital often overlooked role in the reproductive cycles of native flora. By crawling deep into the specialised chambers of flowers to drink sap and consume pollen they facilitate the transfer of genetic material between plants that larger pollinators such as bees or butterflies might miss entirely.
Their mouthparts are uniquely asymmetrical designed to punch into plant cells and suck out the contents a feeding strategy that makes them highly efficient at utilising the concentrated nutrients found in the floral understory. This represents a state of atmospheric tension where their sudden swarming presence acts as a living barometer for the New Zealand summer.
Their life cycle is a marvel of rapid development allowing them to capitalise on the brief high-energy windows of the flowering season. Not threatened thrips are essential components of the broader invertebrate food web serving as a primary food source for predatory mites ladybirds and lacewings.
To encounter a thrips emerging from a petal is to witness a survivor that has mastered the art of atmospheric connection a creature that proves you do not need a large wingspan to be a significant participant in the largest weather patterns of the land.
