Nongame & Rare Species Program The Nongame and Rare Species Programs focus is Texas' rich diversity of nongame animals, plants, and natural communities. Our biologists collect, evaluate, and synthesize significant amounts of data to better inform conservation decisions and formulate management practices. By taking a proactive approach, we work to prevent the need for future threatened and endangered species listings and to recover listed species.

Among the insects inhabiting endorheic, temporary and highly saline small lakes of central Spain during dry periods, tiger beetles (Coleoptera: Carabidae: Cicindelinae) form particularly rich assemblages including unique endemic species. Cephalota dulcinea López, De la Rosa & Baena, 2006 is an endemic, regionally protected species that occurs only in saline marshes in Castilla-La Mancha (Central Spain). Here, we report that C. dulcinea suffers potential risks associated with counter-attacks by ants (Hymenoptera: Formicidae), while using them as prey at one of these marshes. Through mark–recapture methods, we estimated the population size of C. dulcinea at the study marsh as of 1352 individuals, with a sex ratio slightly biased towards males. Evident signs of ant defensive attack by the seed-harvesting ant Messor barbarus (Forel, 1905) were detected in 14% of marked individuals, sometimes with cut ant heads still grasped with their mandibles to the beetle body parts. Ant injuries have been more frequently recorded at the end of adult C.

  • Species Assessment for Northeast Beach Tiger Beetle
    Species Status Assessment Class: Insecta Family: Cicindelidae Scientific Name: Cicindela dorsalis dorsalis Common Name: Northeastern Beach Tiger Beetle Species synopsis: The northeastern beach tiger beetle was formerly common on coastal beaches from Massachusetts to New Jersey and along the Chesapeake Bay in Maryland and Virginia. It is currently confined to a few sites in Virginia and Maryland, and two sites in Massachusetts, having been extirpated from 90% of formerly occupied sites (Schlesinger 2010). It was listed as federally Threatened in 1990. In New York, this tiger beetle was formerly distributed along many of Long Island’s barrier beaches but it appears to have been extirpated entirely by around 1950 (Stamatov 1972). The potential for reintroduction on Long Island was studied by Simmons (2008) who found that although some beaches were intact structurally, nearly all were subject to substantive and pervasive vehicular traffic and were thus unsuitable. Ideal habitat for the adult beetles and their larvae are wide, dynamic, fine sand beaches with little human or vehicular activity. This species was extirpated in NY around 1950 (SGCN Experts Meeting). I. Status a. Current Legal Protected Status i. Federal ____Threatened________ ____________ Candidate: __ No__ ii.
