Trichopoda pennipes, Feather-legged Fly

Trichopoda pennipes, Feather-legged Fly, on Pycnanthemum, Mountain-Mint, in my garden yesterday. Although it’s widespread and common, occurring throughout North America, this was the first time I’ve noticed this species in my garden.
Trichopoda pennipes, Feather-legged Fly, on Pycnanthemum, Mountain-Mint
This photo shows several of the keys to identifying this species:

  • “Feathered” fringes on the hindlegs, true of Trichopoda.
  • Orange abdomen. Females have a black-tipped abdomen. Males, such as this one, have a completely orange abdomen. 
  • Wings are completely black. This species has a transparent margin to the wing.

Trichopoda is a parasitoid of Hempitera, true bugs, including many agricultural and garden pests, such as squash bugs and stinkbugs. For this reason, it’s considered a “beneficial” insect:

Each female fly lays on average 100 eggs, which are placed singly on the body of a large nymph or adult bug. Most of the small, white or gray, oval eggs are placed on the underside of the thorax or abdomen, but they can occur on almost any part of the bug. Many eggs may be laid on the same host, but only one larva will survive in each bug. The young larva that hatches from the egg bores directly into the host body. The maggot feeds on the body fluids of the host for about two weeks, during which time it increases to a size almost equal to that of the body cavity of its host. When it has completed its development, the cream-colored third instar maggot emerges from the bug between the posterior abdominal segments. The bug dies after emergence of the fly, not from the parasitoid feeding, but from the mechanical injury to its body. The maggot pupates about an inch down in the soil in a dark reddish-brown puparium formed from the last larval skin, and an adult fly emerges about two weeks later. There can be three generations per year depending on location.

The fly overwinters as a second instar larva within the body of the overwintering host bug. Adult flies emerge in late spring or early summer. The only bugs large enough to parasitize at this time are overwintered adults. Subsequent generations develop on both nymphs and adults of the next generation.

Scolia dubia, Blue-Winged Digger Wasp

Scolia dubia, Blue-winged Digger Wasp, on Pycnanthemum, Mountain-Mint, in my garden.

Another little jewel of a wasp that is new to me this year. I’ve been seeing it on the Pycnanthemum, but was unable to get decent photos of it until yesterday. I’ve also seen it on the Clethra alnifolia, Summersweet in my garden, which just started blooming in the past week.


With the wings held back, the blue iridescence of the wings might lead one to mistakenly identify this as a small Sphex pensylvanicus, Great Black Wasp.

But once the wings spread to the sides, the exposed abdomen distinguishes it. The cinnamon- colored abdomen and two bright yellow spots make for a clear identification, once you know the species.

Adults feed on nectar, which both the Mountain-Mint and Summersweet offer in abundance.

Females dig in search of grubs of June Bugs and Japanese Beetles to parasitize with their eggs. The wasp larva feeds on the beetle grub and overwinters as a cocoon, emerging the next year.

This species is another example of the importance of providing habitat for wasps in the garden; they are natural bio-controls of other insects that might otherwise overwhelm the gardener’s intentions.

What’s a tree worth?

You can quantify the relative benefits of an individual tree, and project its future benefits as it grows through the years, with i-Tree Design:

i-Tree Design (beta) allows anyone to make a simple estimation of the benefits individual trees provide. With inputs of location, species, tree size and condition, users will get an understanding of the benefits that trees provide related to greenhouse gas mitigation, air quality improvements and storm water interception. With the added step of drawing a house or building footprint—and virtually “planting” a tree—trees’ effects on building energy use can be evaluated.

This tool is intended to be a simple and accessible starting point for understanding individual trees’ value to the homeowner and their community.

Using it is straightforward:

  1. Enter a street address.
  2. Select the common name of the tree species or genus.
  3. Enter the size, indicated by DBH: diameter at breast height (5′ off the ground).
  4. Select the general health or condition of the tree, from “Excellent” to “Dead or Dying.”

The results are returned quickly. Details are available from the different tabs.

The application requires Flash to be supported and enabled in your browser, so it won’t work behind many corporate firewalls.

Updated 2010-08-05: Added links to more reports on the press conference, variously reported also as a demonstration, protest, or rally.


Beets

Yesterday morning, I joined about 70 of my fellow community gardeners and community garden advocates and supporters on the steps of City Hall. The agreement that has largely protected community gardens in NYC since 2002 expires next month. The press conference was organized by the New York City Community Gardens Coalition (NYCCGC) to draw attention to issues with proposed new rules for NYC’s community gardens.

NYCCGC has all the details on their Web site. I urge everyone to weigh in with written comments, whether submitted through the NYC.gov Web site, or by email. You can also (gasp!) mail a letter. You can even call 311. The hearing is Tuesday, 8/10. If you want to speak, you must register by Monday, August 9. All comments are due on or by August 10, the date of the hearing.

Slideshow

Despite the heat, even at 9:30 in the morning, it was a lovely, energizing, and community-building event. The gardens were well-represented.

Design Drafts for the Parsonage at the Flatbush Reformed Church

This afternoon at 3pm I’ll be presenting to the community drafts of two alternative designs for a new communal garden on the grounds of the Parsonage, a landmarked historic building, on the grounds of the Flatbush Reformed Church.

Neither of these is a final design. They’re intended simply to present key features requested by community members at the Visioning Workshops and show how they might integrate into a cohesive design. The two designs weight these features differently, giving more or less space to different areas, and supporting different activities. I’m hoping this afternoon’s meeting will highlight the most popular features of each design, which can be recombined into a final design for this garden.

Dimensions

Here’s the base plan, drawn to scale at 3/16″ = 1 foot, of the site. Kenmore Terrace is at the bottom of the plan, East 21st Street on the left, the parking lot on the right. North is roughly up.

The Parsonage, Garden Design Base Plan

The front porch is nearly 53′ long! It’s just over 25′ from the fence along Kenmore Terrace to the front of the porch, and 27′ from the East 21st Street fence to the side. It’s nearly 85′ from the parking lot to East 21st. The sidewalk bed along Kenmore Terrace is 3’6″ deep. The bed between the fence and the parking lot is 8’3″ deep.

Existing Conditions

The Parsonage, Existing Vegetation

The space is dominated by large, mature oak trees which provide high shade over the entire property. Three large Taxus, Yew, shrubs exist as foundation plantings in front of the porch. There probably was at one time fourth shrub, at the far left of the porch, to complete the symmetry.

Everything else is lawn. Between the parking lot and the center walk, the lawn is sparse and the ground is compacted. To the left of the center walk, the ground is less compacted, and the grass transitions to a mix of clover and moss closer to East 21st Street.

There are planting beds between the fence along the property line and the sidewalk. Existing plantings of perennials in these beds are scattered and sparse.

Design A: “The Commons”

The Parsonage, Garden Design: The Commons

This design maximizes space to meet, sit and play. A paved patio area is created between the center walk and the parking lot. Benches provide seating for over 20 people. A large expanse of lawn provides space for running around or lawn games, such as badminton, horseshoes, etc.

Raised beds – 4×4 or 2×4 – provide over 200 square feet to grow food, herbs, and medicinal plants.

The existing large Taxus, Yew, shrubs are preserved. A buffer of perennials is created around the trunk of each Quercus, Oak, tree.

Rainwater is collected from the downspout near the western end of the porch (left in this rendering).

Design B: “Sanctuary”

The Parsonage, Garden Design: Sanctuary

This design provides for both shared and intimate experiences in the garden. Three gardens are created here: a common area, a wildlife habitat garden, and a rain garden.

The existing Yews are removed to make more room, especially for the common area between the center walk and the parking lot.

A few raised beds are specified in this design in the common area. More space is available for raised beds to the right of this plan, between the parking lot and the fence along the property line.

The common area has both a paved patio area and a small lawn for picnicking.  A wide entrance and semi-circular bench around the base of one of the Oaks provides a generous invitation to enter and linger. No other seating is specified, but could be added, for example, on the ends of the raised beds.

The wildlife habitat garden is contained with a meandering path. Two small understory trees provide focal points. These would be underplanted with small shrubs, and shade-loving perennials. The path is designed to both cutoff and provide access to this garden. You can’t see everything without walking the path. Two benches provide intimate seating, out of sight of each other and other areas of the garden.

Rainwater is collected from the downspout near the western end of the porch (left in this rendering). Here, a “stream” is designed to direct overflow to the rain garden. This would be planted with native shrubs, ferns, and wildflowers.

Proposed NYC Rules Threaten Community Gardens

Update 2010-07-28:


The Baltic Street Community Garden in Park Slope, as it appeared in July 2008. It was destroyed in 2009 by the NYC Department of Education.
Baltic Street Community Garden

The agreement that has largely protected New York City community gardens for nearly a decade expires this September. Community gardens fall under different jurisdictions, depending on whether they are in private hands, such as a land trust organization, or on land controlled by an Agency of the City. In advance of the expiration of the agreement, the NYC Department of Parks and Recreation (DPR, or simply “Parks”) and Housing Preservation and Development (HPD) have drafted revised rules for governing the gardens under their care. In short: gardens will have no protection.

Public comments are due in writing by August 10. To view the proposed rules, or to submit comments:

  1. Visit Proposed Rules on the NYC.gov Web site.
  2. For “Agency”, Select “DPR” or “HPD”.
  3. Click [GO].
  4. Click “Community Gardens” to view the Proposed Rule (PDF). Click “Comment” to submit your written comments online.

There is a community meeting tomorrow evening for gardeners and advocates of NYC’s community gardens to learn about the issues and what we can do in response.

Brine Garden, Pawling, NY

A path in the Brine Garden in Pawling in Dutchess County, NY, north of New York City.
Path, Brine Garden

Last Sunday, Blog Widow and I drove up to Pawling, NY and spent the day with a friend of ours. I also got to meet Julia and Duncan Brine. In their landscape design firm, they specialize in native plants, so I was excited to meet them and visit their gardens.

The gardens ramble over six acres. In contrast to the familiar limitations of urban gardening, it may as well have been 600 acres. The property slopes, steeply at times, from the unpaved entrance drive down to Route 22. Water flows through the property. The day of my visit, precipitation seamlessly cycled through mist, drizzle, sprinkles. There was nearly a film of water over the gardens. I’m not exaggerating. My friend’s sneakers became soaked just from walking through the long, wet grass. And it was wet enough for this fellow to crawl over the ground to his burrow of mud at the base of a log.

Crayfish, Brine Garden

With the almost constant rains we’ve had this summer, everything was lush, full, and green. The rampant growth encroached from all sides, overtaking and disguising any intended boundaries of the cleared areas. This contributed to the fluid expression of “path” at play in the Brine Garden. Narrows suggest passage; wider bays encourage a slower pace.

Study Guide for BBG Plant ID Class

Clerodendrum bungei Steud., Rose Glory Bower
Clerodendrum bungei

This Wednesday I take the final for the Brooklyn Botanic Garden’s Herbaceous Landscape Plant Identification class. [Spelling counts! So please let me know of any typos.] Thursday, I start Urban Garden Maintenance, the last of the eight classes I need for my Certificate in Urban Horticulture from BBG. I started the program in Winter 2008. This is the home stretch; I can’t believe I’m almost done with it.

Unlike the “woodies” class, I already knew most of the plants introduced in the class over the past five weeks. Either I’ve grown them myself sometime over my 30 years of gardening in NYC, or I’ve researched and studied them. However, there have been several, such as the interesting Clerodendrum above, which I’ve never even heard of, or never knew the names of.

This post is the index to my photographic study guide. Plant names are listed by week, in alphabetical order by botanical name within each week. Botanical names are given, corrected for typos, as they were introduced in the class; that’s what we’ll be tested on for the final this Wednesday evening. Plant names are linked to my Flickr Set, where I have one. You can also browse my Flickr Collection for this class, where all the plants are listed by botanical name.

Week 1, 2009.07.22

Callirhoe involucrata, Purple Poppy-Mallow
Callirhoe involucrata, Poppy Mallow

Observed:

Omitted (these will not be included on the final):

  • Aquilegia canadensis, Columbine. This grows as a Spring ephemeral in our region; none were available to observe at this late date.
  • Geranium macrorrhizum, Bigroot Geranium. Omitted primarily for time constraints; also, it was out of bloom by this time of the year. Too bad, since it’s a handsome plant, and there are lots of them around the grounds of BBG.

Week 2, 2009-07-29

We got 11 plants this week to make up for being two short the previous week.

Week 3, 2009-08-05

Week 4, 2009-08-12

This was the only themed week of the class, consisting solely of grasses, ferns and fern allies.
