Collected 5 individuals on 6/10 to rear from stems based on plants showing signs of larvae present. Reared in original stems at first, then switched to carrot and potato. Of the 5 collected, two survived to pupate and ultimately eclose. Two shriveled up prior to pupating, one produced a fly pupa. Of the two that survived, one pupated on 8/16, the second sealed off a chamber within the potato on 8/20 and had pupated by 8/26. First adult eclosed the night of 9/18, second adult eclosed the night of 9/29. Subsequently released. All observations after the initial wild observation marked captive/casual and can be found in the Observation Group field. |

Tagging a few more heavy users of this data field: @christine123 @mws @joebartok @crgillette @ansel_oommen @harumkoh @kens18 @fabienpiednoir @larry522 @spritelink @molanic
Does anyone object to merging this data field with "Host Plant ID" (https://inaturalist.org/observation_fields/6586). Both are "taxon" type fields and really this field (Insect host plant ID) is just a more specific version of "Host Plant ID". I don't think we would lose any functionality (you could query for insect records with a host plant ID field filled out).
Sincerely, I don't know. I've been used with "Insect Host Plant". Can't figure how this will affect data losses to switch to a different field.
I don't see eitheir any need to merge the two : if one is dissatisfied by this one, why then not simply drop it and use the other one ? What does this bring to merge the two ?
By merging the two it makes it easier to search for host plant records. Right now, it could be buried in two different (but essentially the same) fields requiring at least two different queries. If the two get merged, anywhere that currently uses Insect Host Plant will be replaced by Host Plant (e.g. if a project currently uses insect host plant, it will become host plant). Generally, if there is not a need for two different fields (which so far no one has raised) then it is better to simplify and use a single field.
I just want to clear this up - there's basically zero work involved for people here. You certainly would not have to change any records - merging the two fields would transfer the value from "insect host plant" to "host plant ID".
The only difference would be the name of the field. It will not change the actual data.
The problem we would be "fixing" is to consolidate the information. Here's an actual example: right now if I want to find records of the butterfly Danaus plexippus on Common Milkweed (Asclepias syriaca) I have to do at least two queries; one for records of Danaus plexipus with Insect Host Plant = Asclepias syriaca and one for records of Danaus plexippus with Host Plant ID = Asclepias syriaca because users might have used either observation field.
If we can merge these two data fields, all of the values in Insect Host Plant will be transferred into Host Plant ID, so a single query would return all of the results of the two above.
I hope that makes sense. It is to help improve how easy it is to find information in iNaturalist. The only actual work involved is we can't do the merge until there are no projects with "Insect Host Plant" as an observation field (there are four projects currently using Insect Host Plant) there is nothing anyone else needs to do.
In the situation you're talking about, problem is actually that users used a field while there was already one for the same issue...
How would you prevent this to happen again, and people to create new similar fields ? Not to mention that fields can be designed for a peculiar purpose, and thenafter used in a different way...
An obs. can actually have various fields, even with the same value.
In the example above, If I want to work on Danaus on A. syriaca, I'll review D. plexippus obs., and add the field "Insect host plant" on the ones where it is missing. I know you will say that's a lot of work, maybe futile, but how could you, elsewhere, know every obs. is filled, and properly field ?
The problematic project has been deleted. So now feel free to do anything you're judging usefull and necessary. I expressed myself on this, and I have nothing to add.
