The imperative "build" above is the translation of the Arabic word "attakhithi", which is feminine form (Arabic unlike English, differentiates between the sexes). The feminine form is used when all of those it refers to are female, whereas the masculine is used when a group consists of at least 1 male.
Therefore the Quran is in fact saying "build, you female bees.." A swarm of bees (which collect honey and build the hive), are female only. Thus, the phrasing of this command is in agreement with the Fact that male bees do not partake in the construction of the hive.
Let us for a while be one of those who reflect and think about the wonders of Allah (swt) and what He in His supreme wisdom, created. We may compare our factories to the factories of Allah (swt). The lovely honey bees may be small, yet quick and efficient. When they fly it seems as if they are programmed, following the tracks ordained for them.
For a pound of honey around 2 million flowers are visited by the bee. So next time we gulp down that liquid maybe we can be grateful for all that went into producing it and realize the numerous favors of Allah (swt) on us. They travel about 50,000 miles. At the first step the liquid is like water, which is then fluttered upon by their wings till a sweet liquid is left. They then suck it and by using their special glands convert it into honey. Once ready the honey is packed into its special compartments in the hive and sealed with wax thus becoming secure.
Such a small insect makes such a pure thing, so what have we done or are proud of? There are many characteristics of a bee that man can learn from and the wise already have them embedded in them. The following is a comparison between the two and we pray that Allah (swt) also helps us to learn from them and be like them - Ameen
