Reproduction Pattern

However, in so many cases the male yellow jacket die immediately after copulation and the fertilized female queens has to relocate to a safer place to hibernate especially in the winter season. More studies revealed that, the month of April or May is the period when the queens can lay up 20 to 40 eggs or more, the eggs will then produce the first generation of sterile – which is called “female workers.” The queen will continue to reproduce more eggs until the summer season ends, and are able to produce up to 250,000 colonies in a year.
