  Another remarkable and varied selection of invertebrates by Ian Cooper, February 22, from *Colquitz River Park or #by7 the 9 km marker on the Galloping Goose Trail in View Royal.   The first is a nematode – a first for Invertebrate Alert.  Nematoda is a Phylum, divided into Classes, Orders, etc., so we are a long way from being able to identify this one to species!


Nematode (Phylum:  Nematoda)  Ian Cooper

# European Sowbug  Oniscus asellus (Isopoda: Oniscidae)   Ian Cooper

* Grey Field Slug – Deroceras reticulatum (Pul.: Agriolimacidae)   Ian Cooper

*Unidentified Harvestman (Opiliones)   Ian Cooper

# Forest Spider – Pimoa altioculata (Ara: Pimoidae)   Ian Cooper

# Linyphantes sp. (Ara.: Linyphiidae – Linyphiinae)   Ian Cooper

Ian writes: I see many impossibly small spiders like this who have built their delicate webs in the leaf litter. They’re so tiny, it seems futile to try photographing them, but they’re an integral part of the forest floor ecosystem nevertheless.
