The U.S. Fish and Wildlife Service has awarded Advanced BioConsulting a series of competitive grants supporting a partnership to re-establish a population of the Northeastern Beach Tiger Beetle on Sandy Hook, New Jersey. This species was once abundant across the Northeast Atlantic coast, and now the protected semi-natural beach of Sandy Hook (a historic location for this species in view of Staten Island, and Brooklyn) is among its last potential habitats. A population at this site may be the most geographically valuable location for this species, in this region, based on its current and historic distribution.

The team at work

This project will translocate larval beetles from a large population at Monomoy National Wildlife Refuge (MA), with the expectation that they will pupate at Sandy Hook, and emerge as adults to re-establish a population. This work is accomplished in cooperation with many agencies, and personell including: the U.S. Fish and Wildlife Service, The National Parks Service, Monomoy National Wildlife Refuge, the States of New Jersey and Massachusetts, The University of Massachusetts, Amherst, and the generous expertise of academics, contract-biologists, students, and volunteers.

Heading out

 

Project History:

The Northeastern Beach tiger beetle, Habroscelimorpha dorsalis dorsalis (formerly known as Cicindela d. dorsalis), thrives in the harsh, dynamic environment of New England coastal beaches. This species is voraciously predacious, both as larvae who live in the sand and as adults who use their large eyes, sharp jaws, and long legs to chase and attack prey. First described in 1817 by the famous American naturalist Thomas Say, as “On the sea beach of New Jersey; numerous.” (Say, 1817) it was subsequently seen as “abundant on open sandy seashore” (LeConte, 1857), “occurring in great swarms” (Leng, 1902), and in “immense numbers” (Fox, 1910). By the early 1970’s it was believed in danger of extinction from recreation, beach-cleaning and shoreline modification (Wilson, 1970; Stamatov, 1972; Boyd 1979; Boyd & Rust 1982; Leonard & Bell 1999). Subsequent research (Knisley et al., 1987) contributed to its listing as a Federally Threatened species in 1994 (USFWS: 1990, 1994). Currently, this species only exists in only two separately-managed populations: 1) on narrow bay-beaches in the Chesapeake Bay and 2) broad ocean-beaches in Massachusetts (USFWS 1994); and these populations are recognized to have ecological, behavioral, and genetic distinctions (Nothnagle & Simmons 1990; Vogler et al. 1993; Vogler & DeSalle 1993; Pearson & Vogler 2001; Goldstein & Desalle 2003).

Sample area

Conservation efforts to re-establish populations in the late 1990s, and early 2000s resulted in the first translocation attempt for any tiger beetle, bringing over 2000 Chesapeake Bay beetle larvae to Sandy Hook, NJ (Knisley & Hill 1999). Sandy Hook is an ocean-beach located mid-way between the extant populations, and protected by the National Park Service (NPS). For this work the Chesapeake population was used as a source because of its’ large size relative to the single, small, population known in Massachusetts at that time. This translocation lead to several years of population growth on Sandy Hook, then subsequent decline, where expert surveys in 2017-2018 (performed collaboratively with USFWS & Advanced BioConsulting) confirmed the absence of H. d. dorsalis at this site (Gwiazdowski & Knisley, 2019: Unpublished report to the USFWS NJFO). The cause of this decline is uncertain but is a presumed incompatibility of bay-beetles to survive on a seasonally dynamic ocean-beach (Knisley et al. 2005).

Collection sample

Fortunately, a second translocation project during 2000-2003, using techniques developed for the Sandy Hook translocation, brought comparatively low numbers of larvae (<150 total) from the small Massachusetts population to Monomoy National Wildlife Refuge (NWR) (Nothnagle, 2000; Davis, 2003) resulting in a current population estimate of >5-10+ thousand beetles (Kapitulik, 2012; Matthew Hillman – personal communication).

 

Project Goals:

A four-year translocation project is underway using the Monomoy NWR population as an ecologically and genetically appropriate source with the goal of re-establishing the Northeastern Beach tiger beetle at Sandy Hook, New Jersey. This project has three aims: 1) Conduct consecutive larval translocations of up to 300 larvae each year during, 2020, 2021, and 2022; 2) conduct annual surveys during 2020, 2021, 2022, and 2023 for adults and larvae to estimate the effectiveness of the reintroductions; 3) refine and test reintroduction protocols for NBTB larvae, and present them as a model for future translocations of NBTB, and other tiger beetles.

The Puritan tiger beetle (PTB, Ellipsoptera puritana) has only one viable population in the Connecticut river – where it used to be widespread. To restore this species, Advanced BioConsulting leads a team of federal and state agencies, scientists, artists, subcontractors, students and volunteers to learn more about the beetle’s biology, secure good habitat, and establish new populations.

Recently, we completed a large multi-year project which identified quantitative habitat data for PTB habitat quality (prey & sediment), and created the first tiger beetle captive-rearing laboratory – used to reintroduce >1K PTB larvae. <This work was reported on the front page of the NY Times.>

Currently, we’re identifying conservation land, planning to modify new habitat, and understanding how climate change will influence PTB habitat on the river.

On Sandy Hook New Jersey, a barrier-island spit near Brooklyn, the Northeastern beach tiger beetle (Habroscelimorpha dorsalis dorsalis) hadn’t been observed for several years. Advanced BioConsulting, in collaboration with the USFWS, and the National Parks Service, lead a two-year (2017-2018) multi-season survey for adults, and larvae, concluding the species is extirpated from this site.

Advanced BioConsulting provided phylogenetic analysis, all data-graphics, and a methodological framework for a recent publication describing four new cryptic-species of North American tiger beetles. Tiger beetles are thought to be well-known in North America, and the results from this study reveal there is much more to be learned about species-diversity in this group.
