The purpose of this project is to compile observations with evidence of phoresy (one organism using another for transportation).

Do note that phoresy/phoresis is commensal by definition (benefit for one organism, neutral for the other). Although the nature of a relationship between two organisms is hard to assess in images, observations can be added through better judgement (e.g. if an egg parasitoid is found on an adult organism, this is probably commensal).

Other relationships such as symbiosis and parasitism should not be included in this project. Parasites can go into the broader project linked below:
