Another year of species inventory comes to an end. What happened in 2022?
To date, we’ve found and recorded 3412 species that share Metchosin with Homo sapiens. In the course of the year 2022, some 350 people made over 5000 iNaturalist observations within the bounds of Metchosin and Race Rocks. Almost half of these observations were of sufficient quality and accuracy to add to the permanent record. Some 600 experts from around the world chipped in to help identify the posted observations. These 2000+ observations represented about 1000 different species, and of the 1000 species, 130 of them were totally new to the Metchosin database.
What did we identify in Metchosin for the first time in 2022? A quick review.
Mammals. Adding new mammals to the database is unusual. We increased the count by one, though. One of our observers, Maurice Robinson, added the infamous brown rat (aka Norwegian or sewer rat), the scourge of many farms and towns. The American mink was already in our records but both David Bell and Liam Ragan took excellent 2022 photos of this charismatic weasel relative.
Slime Moulds. Robin Banks posted an observation of a slime mould, chocolate tube slime, Stemonitis splendens, that we didn’t have yet.
Insects. Several beetles appeared in our records for the first time. We added new species of click beetles, lady beetles, longhorn beetles, bark-gnawing beetles, sun beetles, ground beetles, checkered beetles, and jewel beetles. For the moths, we found a twirler moth, a curved-horn moth, a satyr moth, a snout moth, and a house moth that were new. There were two new flies, a horse fly and a robber fly, as well as two new wasps, a crown borer wasp and a cross potter wasp. A lygus bug and a seed bug made the list. A damselfly we had not seen before, the western forktail, and a new dragonfly, a pondhawk, turned up. We also found new species of tunnel spider, aphid, leaf miner, leafhopper, springtail, gall midge, and woodlouse. Several observers spotted European praying mantises this summer—these insects must have been unusually abundant.
Plants. On the plant side, James Miskelly found several new species for our Metchosin records. One was Lamarck’s bedstraw (either Galium divaricatum or G. pariseinse). He also found our first quaking-grass, Briza minor, our first American eelgrass, Vallisneria americana, our first humped bladderwort, Utricularia gibba, and our first round-leaved sundew, Drosera rotundifolia. Sundews are usually found in boggy areas, which are rare in Metchosin. We also found a cancerwort, two new sedges, water horehound, bur-reed, and a mint.
Marine life. Garry Fletcher managed to snap a picture of a crystal jellyfish, Aequorea victoria, at Parry Bay. Karen Cram gave us a first look at a new nudibranch, the BC doto, Doto columbiana. Connor (cwardrop) noted a new red seaweed, Grateloupia californica. Terry Carr found an eelgrass isopod, Pentidotea resecata. Tom Hlavac, a diver and retired fishery officer, was able to snap a picture of a giant pacific octopus, Enteroctopus dofleini. Two people submitted records of our first great sculpin, Myoxocephalus polyacanthocephalus. In addition, we had a new anemone, a wolf eel, and a red velvet sponge.
In all, then, a great year. The Metchosin Biodiversity Project hopes that many more Metchosinites will take up their cameras and smartphones and help us count in 2023.
