Summary
Philodromus is a genus of philodromid crab spiders, characterized by their flattened bodies and widespread distribution across the Holarctic, with over 250 described species. This genus includes a variety of species adapted to different habitats, with distinct identification features and ecological roles.
Physical Characteristics
Distinctively flattened body shape, 2nd leg clearly less than two times longer than the 1st leg. Anterior median and lateral eyes are about the same size, and the distance between the 2 posterior median eyes is greater than the distance between posterior median and lateral eyes.
Identification Tips
Look for the abdominal dorsum of P. rodecki which is covered with patches of orange pubescence interspersed with dark, round punctations. This distinguishes it from P. rufus.
Habitat
Commonly found in various habitats throughout the Holarctic region; some species are arboreal and others inhabit ground-level environments.
Distribution
Distributed throughout the Holarctic region, with some species found in southern regions, certain parts of Africa, and sporadically in Australia. Only one species (P. traviatus) is reported from northern South America, 16 species occur in Central Europe.
Diet
Predominantly insectivorous, preying on small insects.
Life Cycle
Life cycle details are not specifically covered in provided data; typical life cycles of spiders include egg, juvenile, and adult stages.
Reproduction
Details regarding specific reproductive strategies are not provided; most spiders exhibit typical arachnid reproduction with mating followed by egg-laying.
Predators
Potential predators include larger spiders, birds, and other insectivorous animals.
Ecosystem Role
Philodromus spiders play a role in controlling insect populations as predators.
Collecting Methods
- Hand collecting from vegetation
- Using sweep nets
Preservation Methods
- Ethanol
- Freezing
- Desiccation
Evolution
Part of the family Philodromidae; species have adapted to various habitats across different geographical regions.
Misconceptions
Some species may be confused with other similar-looking spider families due to their flattened bodies and arboreal habits.
