Direct users to Phenology tool

[Megachile]

I'd like to add some kind of banner or something to the Identify page (possibly also the gall pages?) letting users know that the phenology tool exists and linking to it. Something like this for text?

"Explore the seasonal timing of gall development and emergence with our phenology tool"

and link here (I've combined them into a single tool so the other one is defunct):

In the long term it would ultimately still be ideal to integrate the pheno data into the site somehow but this is an adequate solution in the medium term.
