A number of lupin plants in my garden are smothered with green aphids, which I am eyeing up as food items for small newts. Do aphids incorporate any plant toxins in their bodies from their host plant, and if so, does this leave aphids feeding on lupins safe or unsafe for amphibian food items?

Thanks

Chris

Can´t remember for sure(it´s been two years since i studied this) but i think toxicity varies a lot between species. If you can find out the exact Lupinus species, you may be able to know if they pose a threat.
Anyway, aren´t the pods what´s toxic? If the alkaloids are not present in the sap, then there´s no problem.
Sorry i can´t give you a definitive answer....

Depending of the species all parts of lupine plants are light toxic to toxic, seeds VERRY toxic

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
