Example of invertebrates that are attracted to heat?

Question

I would like to test a device that outputs heat in order to attract schistosome parasites in water. However, I would like to use a substitute, since I cannot find schistosome parasites for sale. **Are there any organisms that are attracted to heat and are easily accessible?**

Answer 1

If the device does not need to be used in water, and instead can simply be exposed directly to air, I think mosquitoes would make a great substitute.

If it does need to be submerged in something, just not in water, nematodes in soil would be a good substitute.

If it needs to be submerged in water, aquatic larvae of some sort would probably suffice.
