Entomophily
Definition
Insect pollination. Entomophilous plants produce sticky, often echinate pollen in smaller quantities. Because it is not designed for aerial travel it does not accumulate in background pollen rain, making its presence on clothing or skin more significant as a transfer indicator.
- Meaning
- Insect pollination
- Pollen traits
- Sticky, often echinate, produced in smaller quantities
- Forensic value
- Not part of background pollen rain, so a stronger transfer signal
Common questions
Why does entomophilous pollen make a stronger forensic indicator than wind-borne pollen?+
Wind-pollinated (anemophilous) species shed huge quantities that drift widely and settle as background rain on almost any surface. Entomophilous pollen is not built for aerial dispersal, so finding it on clothing or skin points to direct contact with the source plant or its immediate vicinity.
Does entomophilous pollen still need a palynological reference collection to identify?+
Yes. Its distinctive sticky, spiny surface helps distinguish it under the microscope, but species-level identification still relies on a reference collection or key, the same as for any other pollen type.
