My own difficulty in identifying specific Melilotus species was greatly assisted by csledge, an iNaturalist I have never met. She identified an observation I had posted, including an exhaustive botanical reference list that is amazingly handy!
Here's her ist of online resources as a starting place for identifying MN and N. American species: https://www.inaturalist.org/journal/csledge/55746-a-list-of-online-resources
Many thanks csledge!
Dactylopius
Cochineal Scale Bugs
Genus Dactylopius
Dactylopius coccus is not recorded in the US. There are four species of Dactylopius in California and they will typically need to be slide-mounted for species-level ID. True cochineal has a light dusting of wax and the female bodies are visible:

I should have known this...
Also, with thistles, their relatives, and Asteraceae as a whole, please try to get a good photo of the phyllaries (which you can do with a side-view of the flower head)! The phyllaries are often one of the best features for ID.
These iNat folks are known as "efmer". They are a MOST EXCELLENT resource for flora of Anza-Borrego Desert.

Fascinating discussion on complexities of identification.

ALWAYS something new!
This morning I read the following FASCINATING article from a friend of mine:
https://missiontimescourier.com/the-invasive-italian-white-snail/
I then went out to the park, photographed and posted an iNat obeservation of same.
I was quickly reminded (again) that there were MANY iNaturalists with far greater expertise than I have....

And of course comes THIS little biological tidbit: https://en.wikipedia.org/wiki/Love_dart
Scientific name
Centaurea melitensis
Additional name information:
L.
Common name
tocolote, Maltese star thistle, Napa star thistle, Malta starthistle
Tocolote was brought to California during the Spanish mission period. The earliest record of its occurrence was seed found in adobe bricks of a building constructed in 1797 in San Fernando (Hendry 1931). It appears to have been a contaminant in wheat, barley, and oat seed and was widely distributed in dry-farmed grain fields. In one instance its seed was found embedded in an oat floret (Stanton and Boerner 1936). Seed is transported by humans, animals, or wind, similar to starthistle (Gerlach unpubl. data).
