This blog provides an informal forum for terrestrial invertebrate watchers to post recent sightings of interesting observations in the southern Vancouver Island region. Please send your sightings by email to Jeremy Tatum (tatumjb352@gmail.com). Be sure to include your name, phone number, the species name (common or scientific) of the invertebrate you saw, location, date, and number of individuals. If you have a photograph you are willing to share, please send it along. Click on the title above for an index of past sightings.The index is updated most days.

   Jeremy Tatum writes:  I don’t normally include sightings and photographs of invertebrates from off-Island on this site, but Sharon Godkin sent a photograph of a tussock caterpillar from Powell River just at a time when I am interested in these caterpillars.  First, here are photographs of two confidently-identified species, posted recently on this site and repeated here:

 

 


Orgyia antiqua (Lep.: Erebidae – Lymantriinae)  Jeremy Tatum

Foodplant: Black Cottonwood

 


Orgyia pseudotsugata (Lep.: Erebidae – Lymantriinae)  Jochen Möhr

Foodplant:  Douglas Fir

Now – an embarrassing admission!  In an earlier version of this posting, I had presented the caterpillar below as another tussock.   It is not even remotely related to the tussocks.  It is a dagger (Genus Acronicta) – a noctuid.

Acronicta impleta (Lep.: Noctuidae)   Jeremy Tatum

Foodplant: Salmonberry

And now, a photograph sent to Invert Alert this morning from Powell River by Sharon Godkin.  I initially assumed that it was O. antiqua, but now I’m not so sure.  O.antiqua feeds on a wide variety of foodplants – trees, shrubs, low-growing weeds, but this one was on Typha, rather unusual for antiqua, so maybe it’s something else.

 

 

Something else?   Sharon Godkin

Foodplant Typha

 

Lastly, since I’ve cheated a bit this morning by going off Vancouver Island to Powell River for Sharon’s caterpillar, I can’t resist going a bit further and showing a photograph of a singularly beautiful Orgyia sent to me by Dr David Wagner from (I think?) California:

   To finish off this morning’s Invert Alert, here are two more views of Ian Cooper’s beewolf first shown yesterday:

    I asked David Harris (Newhaven, Sussex, England) whether there are beewolves in England and he replied:  Not only do we get Beewolves over here, but I think Newhaven must be the Beewolf city judging by the hundreds we have seen on our local nature reserve so far this year. I will dig out some photographs my friend Pete has taken of them recently. Locally some of ours have the yellow behind the eye rather than the more normal red.  And we found one the other day bigger than a Hornet.  Despite the text books saying they only feed on Honeybees, here this is just not true. I`m sure they must take some, but locally they seem to go for Yellow – legged Mining Bee and also linger well into November feasting on Ivy Bee. Again, not mentioned in the text books!

 

More this afternoon…
