“…In addition, Drosophila may not provide adequate nutrition for egg development in tiger beetles as seen in some ground beetles (Jorgensen & Toft, 1997). In laboratory studies, average fecundity for tiger beetles was estimated to be between 10 and 50 per adult for eastern North American species (Shelford, 1908), between 20 and 50 for Arizona species (Knisley & Schultz, 1997), and up to 310 for a large Oriental species (Hori, 1982).…”

“…Schultz (1989) found that larvae of eight sympatric Texas cicindelid species occurred in one of four specific soil types, but the mechanism for this partitioning was not determined. Other studies have reported that larvae of co occurring species are segregated based on topography, vegetation cover, slope, soil type, soil particle size, and soil moisture level (Shelford, 1908;Willis, 1967;Knisley, 1987). Non-overlap of larval habitat may be evidence of niche partitioning for sympatric species, but the proximate mechanism for female oviposition has been investigated only in controlled laboratory studies of three species: Cicindela limbalis Klug, C. sexguttata Fabr., and C. tranquebarica Herbst (Shelford, 1908).…”

“…Few studies have examined factors that contribute to tiger beetle oviposition choice (Criddle, 1907(Criddle, , 1910Shelford, 1908Shelford, , 1911Schultz, 1989). Female oviposition preference for soil types and other habitat characteriztics has been observed or inferred based on larval distribution, but field tests have not been performed.…”

Summary 1. Adult tiger beetles of the genus Cicindela often co‐occur within a habitat but larvae do not. Larvae are sedentary and form usually permanent burrows at the site of oviposition where they require 1–3 years for development. 2. To test niche partitioning based on ovipositional preference, the behaviour of two sympatric salt marsh tiger beetles, Cicindela circumpicta and C. togata (Coleoptera: Cicindelidae), were examined. 3. In laboratory studies, female C. circumpicta and C. togata distinguished between experimental salinities, with the former preferring 4 parts per thousand (ppt) and the latter preferring 12 ppt. In the field, C. circumpicta larvae were associated with lower salinities (1–3 ppt) and vegetation along the edges of salt flats while C. togata larvae were found on open salt flats often near halophytes (average salinity = 7.8 ppt). 4. In the field, females chose sites for oviposition in response to shade but not vertical landmarks. In a direct test, 53 of 56 new larval burrows occurred in shaded treatments, three in nonshaded controls. 5. Compared with nonshaded controls, shade increased survival of eggs that were collected in the laboratory and placed in the field. For C. circumpicta eggs, 78% placed in shaded treatments hatched, while significantly fewer (22%) hatched in exposed treatments. For C. togata, 43% of eggs placed in the shade hatched, while no eggs placed in exposed treatments hatched. 6. These results support the hypothesis of niche partitioning between C. circumpicta and C. togata based on ovipositional choice and resulting larval habitat.

“…Unlike most other tiger beetle species, the larvae of Cicindela hirticollis relocate their burrows and are often observed crawling on the sand surface (Shelford, 1908;Knisley and Schultz, 1997). Although the reasons for this movement are not clearly understood, Shelford (1908) found that C. hirticollis larvae would abandon old burrows and dig new ones in response to slight changes in soil moisture.…”

Movement of Cicindela hirticollis Say Larvae in Response to Moisture and Flooding

The larvae of the tiger beetle, Cicindela hirticollis Say, inhabit sandy shoreline areas that flood periodically. This species has declined over much of its range and at least one subspecies is near extinction, possibly as a result of human alteration of waterways. In addition to physiological tolerance for anoxia, the larvae have physical and behavioral adaptations to avoid drowning. We hypothesized that C. hirticollis larvae would exhibit behavioral responses to soil moisture change and flooding because, unlike most other tiger beetles, they frequently relocate their burrows. Our laboratory studies demonstrated that larvae select surface soil moisture levels of 7-50% saturation in which to dig new burrows. Within 96 h of immersion, most larvae abandon burrows and larvae do not form new burrows in darkness. Larvae may relocate when flooded, suggesting a previously undocumented mechanism for dispersal; however, dams often eliminate suitable habitat areas downstream, suggesting that this behavior may be detrimental in riverine populations. Because larvae move during daylight hours, they also are likely to suffer mortality from trampling due to human recreational activity.
