Ammophila
Thread-waisted Sand Wasps
Ammophila is a large, cosmopolitan genus of solitary hunting wasps in the family Sphecidae, comprising over 200 species distributed across warmer regions of all continents except Antarctica. These thread-waisted wasps are characterized by their elongated, slender petiole connecting the thorax and abdomen, and their distinctive nesting behavior involving burrow excavation and caterpillar provisioning. Females construct underground nests in sandy or compact soils, paralyze caterpillars with their sting, and provide this food source for their developing larvae. The genus serves as a host for Strepsiptera endoparasites and is subject to nest parasitism by satellite flies and other organisms.

Bombus fervidus
golden northern bumble bee, yellow bumblebee
Bombus fervidus is a North American bumble bee distinguished by its predominantly yellow coloration on the abdomen and thorax. The species is a long-tongued specialist that forages on flowers with deep corollas, and has been documented visiting over 20 plant genera including milkweeds, goldenrods, and blueberries. It exhibits complex social behavior including coordinated nest defense and worker-queen conflict over male production. Populations have declined significantly across most of its range, with habitat loss to agricultural intensification identified as the primary threat; it is currently classified as Vulnerable by the IUCN.

Dianthidium simile
Northeastern Pebble Bee
Dianthidium simile is a solitary bee species in the family Megachilidae, commonly known as the Northeastern Pebble Bee. It belongs to a group of bees known as resin bees, mason bees, and leafcutter bees, reflecting the diverse nesting materials used by members of this family. The species is native to North America, with confirmed records from the northeastern United States including Vermont. Like other Dianthidium species, it constructs nests using plant resins and other materials, and is subject to parasitism by specialized wasps such as leucospids.

Eumenes verticalis
Vertical potter wasp
Eumenes verticalis is a solitary potter wasp in the subfamily Eumeninae, known for constructing distinctive urn-shaped mud nests. Females build marble-sized clay vessels with fluted necks, provision them with paralyzed caterpillars, and lay a single egg inside before sealing the nest with a mud plug. The larva develops within, feeding on the fresh prey, then pupates and emerges by chewing an exit hole in the side of the pot. Like other solitary wasps, it poses minimal sting risk to humans.

Stenodynerus blepharus
Stenodynerus blepharus is a species of solitary mason wasp in the subfamily Eumeninae, described by Bohart in 1953. The species is currently treated as a synonym of Rhynchalastor blepharus in some taxonomic databases, reflecting ongoing taxonomic revision in this group. As with other Stenodynerus species, it is presumed to be a cavity-nesting wasp that provisions its larvae with paralyzed caterpillars. Direct observations of this specific species in the field are sparse, with only two observations recorded in iNaturalist.
