please save me I don't want to die

Today's round of boring updates:
- I rehydrated a Xanthoria parietina specimen I had in dry storage. It was dead, because it did not become greenish after hydration. That was my last one.

- I did recently take a sample from the unidentified sunburst lichen pictured above, it was from my own city so it presumably doesn't need salt spray like X. parietina does. The unidentified was growing on painted wood, so it can probably grow on other unnatural nutrientless substrates too, like plastic. To decrease the risk that a heterospecific lichen would grow in my culture and make it easier to peel off the wood, I only took the part that was already loose and hanging in the air.

- Cuscuta subinclusa doing well. Nothing interesting has happened.

- Shortly after I posted my last post all the sealed Cryptocephalus sanguinicollis unsealed their cases when I misted them heavily by accident (light misting did nothing). This did not appear to harm them, and now all 4 are eating petals again. I should also mention C. sanguinicollis larvae are prone to destroying (likely eating) each other's cases, seemingly mistaking them for food. This seems to be why the 7 larvae I had went down to 5; the missing larvae left behind cases with big holes in them, and holes in cryptocephaline cases interfere with proper moisture homeostasis and can kill larvae that way. I should note that 2 of the 4 recently had massive holes made in their cases but then managed to successfully fix them without dying; this is because at the 4-5 millimeter stage larvae are relatively hardy compared to newly hatched ones, and because I kept them all lightly damp after noticing the holes so they wouldn't desiccate while trying to patch them. Weirdly enough the holes are not patched immediately, instead they wait a few days before doing so. Also, behavioral notes: larvae kept dry with water-containing food e.g. petals or larvae kept lightly damp well ventilated are lethargic, which seems to be a sign of health. Larvae that are too wet run around energetically a lot and try to circle/climb walls.

- I don't know if I mentioned it before, but the round-leaved Huntington wort died from mold and depression-induced plant neglect. A few ramets of the unknown pincerwort survived and have grown well on wood-rich soil. Evidently this is a case of the fundamental niche being wider than the realized niche, because in the Huntington the pincerworts only lived high up on trees, with various tropical-looking mosses monopolizing the ground.

- More telegraphweed/Datura seeds added to NHMLA. I also brought and planted some Datura seeds at the Junior High native garden.
