Wasp Week Day 1: Eastern Yellowjacket

Eastern Yellowjacket, Vespula maculifrons
Floyd Bennett Field, 2007-09-23

This is a female worker. Color patterns vary on drones and queens.

There are actually several yellowjacket species, and quite a few more wasps that look like yellowjackets. There are even flies that mimic this color pattern to scare away potential predators. Maculifrons used to be the most common “true” yellowjacket on the East Coast and still seems to be around New York City. However, in some areas it is losing ground to the invasive German Yellowjacket, Vespula germanica.

Wasp Week: Day 0

Sunday, October 21st, 2007

I am declaring this to be Wasp Week here on Mokka mit Schlag. I’ll be presenting a new photograph each day of some of my favorite local New York wasps, like this Blue-black Spider Wasp from Hook Mountain. Wasps and bees are much maligned and feared, and consequently I don’t think we pay nearly enough attention to them. However, they’re usually quite harmless as long as you don’t get too close to one or step in a hive. I’ve taken some risks sticking my camera way too close to some of these individuals, so I wouldn’t be surprised if one stung me, but so far the worst that’s happened is that the wasp has flown off to the next flower. (Still, I am thinking it may be time to purchase a camera with a longer lens if I’m going to keep doing this. :-) )

American Bird Grasshopper

Ridgewood Reservoir, Queens, NY, 2007-10-20

Steve Nanz found and later ID’d this monster yesterday at Ridgewood Reservoir. It’s one of the largest grasshoppers in North America. When spooked, it flies into a nearby tree, hence the name. It’s uncommon to rare this far north. Neither Steve nor I had ever seen one before. It seems to be more of a southern species. Possibly like yesterday’s Red-banded Hairstreak, global warming may be pushing its range north.

Red-banded Hairstreak

Small blue-gray butterfly with red and white band
Red-banded Hairstreak, Calycopis cecrops
Brooklyn Botanic Garden, 2007-10-20

This quarter-sized butterfly is only supposed to be a vagrant this far North, but its range has been increasing. I’ve seen it two weekends in a row now in the Botanic Gardens, despite the lateness of the season. It perches on a flower and rubs its wings together in opposite directions, though I’m not sure why. I’ve never seen any other butterfly do this.

Leopard Preorders

Thursday, October 18th, 2007

Apple’s announced that Max OS X 10.5 Leopard is one sale next Friday, October 26. Amazon seems to have the cheapest price: $109 with free supersaver shipping. However, if you order it direct from Apple for $129, it should arrive on Friday. I’m cheap so I’ll probably just wait for it to arrive a few days later from Amazon. I notice items shipped with Super Saver shipping usually arrive faster than the extra 5-9 days they say it will take. I suspect they’re mostly using the Super Saver as a way to distinguish their most price-sensitive customers.

Although I am looking forward to Leopard (especially Spaces, Time Machine, and the new Address Book and iCal) I may even wait till I buy my next Mac to upgrade. Apple may be releasing new MacBooks or desktops in the next few weeks as well, and if they do I may well buy one. If so, there’s no big reason to pay $109 for an OS upgrade for a machine I’m replacing soon anyway.

I do wish Apple would include the new version of iPhoto with the OS. GarageBand, iDVD, and iMovie I can live without, but iPhoto’s pretty important to me, and my version’s getting a bit old in the tooth. I’m not sure where I got it: with one system or OS upgrade or another. I can’t keep track of what’s bundled with what these days, and it’s always a pain when you have to wipe a disk clean or transfer files to a new computer and then discover some of what you thought were bundled apps are now missing. Then again I may be outgrowing iPhoto. It may be time to look into Aperture or Adobe Lightroom instead.

Spotted Cucumber Beetle

These colorful, ladybug-sized beetles can be major crop pests. This is the second one I’ve seen in the area. The first was in Prospect Park a couple of months ago, though I didn’t recognize that one at the time.
