Each bee species is different. Blue mason bees, for example, are only active for 3-4 weeks when the first flowers appear, then they die. It&#x27;s a pretty incredible life cycle: 11 months developing from egg -&gt; larva-&gt; then spin cocoon-&gt; finally a few weeks to forage for pollen and lay their own eggs. There are many species of native bee with short cycles like this. The native bees you see in April will be different than the bees in June, different than in August.
