When is the Best Time to Observe Light cahill
The best time to find light cahill is during their brief adult stage, which often occurs en masse during late spring to early summer evenings, just before dusk. For naiads, they can be found throughout their aquatic life phase which can last up to a year.
Rectangle
What is the Best Weather to Observe Light cahill
Calm, warm evenings are ideal for observing adult light cahill as they engage in mating swarms near water bodies. naiads are less affected by weather but may be more active and visible in warmer water temperatures.

How and Where Can You Find Light cahill at Different Life Stages
Egg Locate where mature light cahill females deposit their eggs, usually in running waters of streams or rivers. Look for them by carefully inspecting submerged rocks or vegetation.
Naiad Light cahill naiads are aquatic and can often be found in riffles or on the streambed in clean, well-oxygenated water. Search for them by turning over stones or using a fine mesh net to sift through the water's substrate.
Subimago The subimago or 'dun' stage of light cahill occurs after the nymph stage and just before full maturity. These subimagos usually rest on nearby vegetation or water surfaces to molt into the adult stage. They can be found by scanning the banks and plants adjacent to water bodies during emergence periods.
Adult Adult light cahill, known as 'spinners', are most active during mating swarms which occur above water surfaces. Look for them flying above or resting on objects near the water, ideally on windless evenings during the swarming season.

Naiads
Light cahill is highly valuable as an environmental indicator, particularly during its naiad stage. These stages are sensitive to shifts in water quality parameters, such as dissolved oxygen and pollutant concentrations, allowing scientists to monitor aquatic ecosystem health. Their presence and abundance can signify pristine conditions, while their absence may indicate environmental stress or pollution, making light cahill an essential tool for water quality assessment.
