Creep Crawly Cav availability

I feel like I’m missing something. Are there just a lot fewer chances to form Cav crystals this month compared to other moths with SQ Cav shards? If so that’s ok, I’m disappointed but not really complaining but I really feel like maybe I’m adding up what’s available wrong or missing a source or something.

the arena runs twice, which is 4k shards from that.
There’s also a calendar with shards that starts today
Edit: it’s still less, but these are somethings worth noting
