Comet Darner spotted despite widespread water impairment

July 19, 2026

(Anax longipes) — North America's largest darner — turned up in the park on July 14, perched along the water's edge in the midday heat. These elegant, long-bodied insects are indicators of clean, healthy aquatic ecosystems; their nymphs, which spend months underwater, cannot tolerate pollution.

What makes this sighting worth noting is the landscape context. All 23 waterbodies assessed within eight miles of here carry federal impairment designations — meaning they are officially deemed too contaminated for their intended uses. Yet this threatened species still holds on in the green corridors threading the watershed, a testament both to the resilience of good habitat and the precariousness of what remains. The parks that shelter this darner are refuges in an increasingly compromised system.

Flowering dogwood feeds the spring insects

May 28, 2026

In the parks near the Upper West Side, the flowering dogwood stands in full bloom against the green backdrop of newly leafed trees. White bracts spread wide like cupped hands, each cluster holding dozens of tiny yellow-green flowers at its center. The air carries the faint sweet scent of nectar, a signal that draws insects from across the canopy and understory.The brown-belted bumble bee arrives with a low buzz, her body thick with the russet band that gives her species its name. She lands heavily on a dogwood flower cluster, her weight bending the branch slightly. Her tongue extends to reach the nectar hidden in each small flower, while pollen grains stick to the branched hairs covering her body. As she moves from flower to flower within a cluster, then from cluster to cluster across the tree, she carries pollen between the separate male and female flowers that make up each white display.This exchange feeds both partners in ways that ripple through the late spring ecosystem. The bumble bee stores nectar in her crop and packs pollen into the baskets on her hind legs, carrying protein and carbohydrates back to her underground colony where workers tend developing larvae. The dogwood receives the cross-pollination it needs to set the bright red berries that will ripen by late summer, feeding migrating birds when insects become scarce. Other native bees join the feast: smaller sweat bees that nest in the ground beneath the trees, and solitary bees that emerge from winter hiding places in dead wood and leaf litter. Beetles climb up from the forest floor, their movements slower but no less purposeful as they chew pollen and lap nectar from the accessible flowers.The dogwood's timing anchors this burst of activity. Its flowers open just as many insects complete their spring emergence, providing concentrated nutrition when other flowering trees have finished their brief displays. The tree blooms for only two weeks, but those weeks coincide with the peak demand from new bee colonies, emerging beetles, and the caterpillars of moths that will pupate in the soil below. Even the invasive spotted lanternfly, now established in these urban forests, feeds on the tree's sap, though it gives nothing back in return.Close your eyes and listen for the steady hum that fills the air around a flowering dogwood. The sound deepens and fades as bumble bees move between trees, punctuated by the higher buzz of smaller bees and the occasional rustle of a beetle navigating between flower clusters. When you open your eyes, watch how the white bracts catch and hold the filtered light beneath the canopy, each tree a bright anchor in the green understory.

nymphs (Lycorma delicata) are actively feeding on both sides of the Hudson this spring — a stark contrast to six years ago when the first individuals appeared here. What began as a curiosity has become a permanent fixture across the region.The lanternfly's success owes much to the landscape itself. (Ailanthus altissima) lines every weedy margin from Jersey City to Lower Manhattan — an aggressive non-native that provides unlimited food for this pest. The combination is ecological opportunity in its starkest form.There is still a narrow window for intervention. At this nymphal stage, before they develop wings and disperse, the lanternflies remain largely vulnerable to targeted management. Once they fledge in late summer, control becomes far more difficult.

(Lycorma delicatula) are at peak abundance across the urban core — over a hundred sightings since late March, with adults now feeding heavily on oaks and maples in Williamsburg, Clinton Hill, Brooklyn Heights, and Lower Manhattan. The insects have spread from a focus point on Governors Island in late spring to establish themselves in clusters throughout Brooklyn and Manhattan within ninety days.Their explosive presence here traces back to an earlier invasion. (Ailanthus altissima), which arrived in these neighborhoods in the 1700s as an ornamental, proved to be the perfect host plant for this invasive pest. Now the lanternflies' honeydew coats street trees in a thin film of sticky residue that fuels sooty mold blooms — blackening foliage on the very maples and oaks that neighborhoods have spent years establishing and maintaining. The ecological cost compounds: weakened urban canopy, pest populations exploding where natural predators are scarce, and no easy way to manage the cycle without broad toxin applications.
