Waved Sphinx Moth – Ceratomia undulosa (Hodges #7787)

I can’t help but get a little excited about sphinx moths; they’re so big and cool looking that I just can’t resist taking a photo (foreshadowing: expect to see more sphinx moth photos by the end of the week). This individual came in while I was blacklighting at the Rouge Valley BioBlitz, right in the heart of Toronto.

The Waved Sphinx Moth feeds on a variety of plants as a caterpillar, including ash (Fraxinus), privet (Ligustrum), oak (Quercus), hawthorn (Crataegus), and fringe (Chionanthus). and can be found across much of eastern North America throughout the summer.

As for parasites, being big and widespread has it’s drawbacks, as this species has at least 10 species of Tachinidae known to develop in it (Belvosia borealis, Compsilura concinnata, Drino incompta, Chetogena claripennis, Chetogena floridensis, Hyphantrophaga hyphantriae, Hyphantrophaga virilis, Lespesia aletiae, Lespesia frenchii and Winthemia datanae).

Happy (Inter)National Moth Week!

The organizers of National Moth Week have done a great job getting people to volunteer to do public moth-related events, so check to see if there’s something going on in your neck of the woods. If there aren’t, that doesn’t have to stop you from mothing; go hang out at bright lights just after dark and see what you can find!

This week should be pretty fun, and I’m going to try and get out at least one night to see if I can’t add to my abysmally poor list of moth photographs, and will try and tweet any encounters I have with moths throughout the week. I’ll also be contributing any new sightings to Project Noah and iNaturalist, so feel free to follow along with me there.

I’ve successfully ignored the Lepidoptera thus far in my entomological career, so I’m taking this opportunity to do a little learning and see if I can’t improve on my moth ID skills. I’m going to be posting photos of moths throughout the week, some from North America which I’ve been able to identify, and some from my tropical travels which I have no idea about. If you notice that I messed up an identification, please feel free to gloat and mock my error; perhaps it’ll teach me not to ignore an entire order of insects from now on…

Oh, and because I can’t completely turn my blog over to moths, I’m going to be featuring their dipteran parasites whenever possible, so expect plenty of tachinid talk this week too!

Happy Mothing!
