Terrestrial arthropods like harvestmen
have a sparse fossil record because their exoskeletons don't preserve well.
Cytogenetic studies of South American harvestmen
were performed in only eight species of the family Gonyleptidae Sundevall (Laniatores) from Brazil, which showed the highest chromosome numbers of the order (Oliveira et al.
Most descriptions of courtship in harvestmen
of the suborder Laniatores lack detailed information, such as which parts of the female body are touched by the male.
Insect larvae (including those of moths, Lepidoptera), centipedes (Chilopoda), spiders (Araneae), ants (Hymenoptera: Formicidae), and harvestmen
(Phalangida) contributed most to the diet of the species.

Alternatively this double peak of activity might also correspond to the same single generation of harvestmen

Bechstein's bats are medium- sized with long, broad ears that help when feeding on "noisy" arthropods including moths, crickets, harvestmen
, earwigs, ground beetles and spiders; the bats often pick these insects off vegetation.
There are more than 600 species of spiders in Britain, and a couple of dozen of their close cousins the harvestmen
- so-called because they are mostly seen in late summer and autumn.
