Well, they don't. Not all species emerge synchronosly, in fact I think your thinking of mayflies.
Whatever the species, it is always for two reasons - to avoid predation by overwhelming your predators and for sex. And I guess also for better gene distribution and offspring survivability (synchronised mating usually occurs before a synchronised hatching/birthing)
What else can I help you with?
Why do dragonflies migrate?

Does a dragonfly moult?
Yes, dragonflies do moult, a process known as ecdysis. They undergo multiple molts during their nymph stage, shedding their exoskeleton to grow larger. Once they emerge as adults, they typically only moult once more, shortly after leaving the water, as they expand their wings and harden their bodies. This process is crucial for their development and survival.
Does dragonflies has a backbone?
if your wondering about back bones, dragonflies do not have them...they have exo-sceletons. Its like scales.
How many legs do dragonflies have?
Like all insects, dragonflies have six legs, arranged in three pairs.
What the steps of the incomplete metamorphosis of a dragon fly?
The incomplete metamorphosis of a dragonfly involves three main stages: egg, nymph, and adult. The process begins when female dragonflies lay eggs in or near water. Once the eggs hatch, the nymphs emerge and live in aquatic environments, where they undergo multiple molts. After several weeks to months, depending on the species, the nymphs eventually crawl out of the water, shed their skin again, and transform into adult dragonflies.
Do dragonflies eat other dragonflies?
yes
