no they can swarm when ever
'Bees will not swarm before a storm' is a very old saying, but there is no documented proof that bees can predict storms. However, bees will not leave the hive if the air temperature is below about 14C (57F), or if the wind speed is more than about 12 miles per hour, and either, or both, of these conditions often precedes a storm.
Different bee species swarm for different reasons. Typically they don't swarm before they die and will only swarm when threatened or when the queen bee leaves the colony with a large group of worker bees.

The sentence could be rearranged to read, "A swarm of bees was chasing me." See the related link for subject/verb agreement rules. Rules 3, 4, and 18 address this question.
Swarm
Flies may seem more active before a storm due to changes in barometric pressure and humidity levels, which can affect their behavior. Some species of flies are believed to have a heightened sensitivity to weather changes, causing them to swarm and become more active before a storm hits.
