Aphids can reproduce without mating during the warmer months of the year.

The longer version

Warm months allow aphids to reproduce without mating, with females producing daughters from unfertilised eggs. Compared with laying eggs that must survive winter, this shortens each generation considerably, so numbers climb quickly while sap-rich growth is abundant.

Because offspring are females able to reproduce at once, one foundress can generate a sizeable population within days. Winged forms appear when crowding rises or plant quality drops, dispersing to fresh shoots. Sexual reproduction generally returns later in the year, producing hardy eggs able to withstand cold and drought. Plants often respond to heavy feeding by growing distorted leaves.
