It Started With Small Melilot

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!

Cochineal FYI (from erincpow)

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:

  • erincpow disagrees this is True Cochineal Bug Dactylopius coccus

Italian Thistle

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.

Invasive Snails and Love Darts

ALWAYS something new!

This morning I read the following FASCINATING article from a friend of mine:

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

Malta Star Thistle "Tocolote"

Scientific name
Centaurea melitensis
Additional name information:


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).

Identify Velvet Ants by Species

In the past I have received more than one spanking for misidentification of species. As of my last post of a Dasymutilla observation, I was able to ask an expert the following:
"What is the visual difference between aureola and magnifica?"
Many thanks to Kevin Williams, CURATOR.

Dasymutilla magnifica has a black head and thorax. It's hard to separate from D. klugii, and those are usually separated by distribution (D. magnifica mostly in California and Arizona hot deserts; D. klugii mostly in New Mexico and Texas).
Dasymutilla aureola is a Pacific species with a short thorax, thick head, and uniform white to red setae on the head, thorax, and abdomen.

  • as well, there are MANY excellent and fascinating photos too be found on the following project:
