A female aphid can give birth to large batches of larvae (see the video). Their development consists of 4 larval stages and one adult stage, with a moult between each one (see the video). The 4 larval stages are distinguished essentially by the size and degree of development of appendages, number of antennal segments, the form and size of cornicles and of the cauda. The cauda of larval stages is either very weakly differentiated from the abdomen or not at all, unlike the adult stage where it is clearly distinct. In future alates, the wing buds do not appear until the 3^rd larval stage. From the birth of the adult stage the development lasts between 8 and 10 days depending on climatic conditions.
An adult lives for 10 to 120 days with an average of 50 to 60 days. It weighs about 1mg.
It can produce between 40 and 60 larvae. Aphid larval development can be summarized as follows:       

Capitophorus horni : different morphs
larva N3 (prominent shoulders)	larva N4 with wing buds and larva L1	alate adult (LV) alate virginopara (LV	apterous adult and larva L1 apterous virginopara (AV)
Takecallis arundicolens : sequence from stage N4 to alate adult stage
larva N4 with wing buds	end of imaginal moult	Swelling of wings	translucent alate adult
After a few hours, pigmentation appears
