Burrow Morphology

Food acquisition in animals that construct burrows for foraging is influenced by burrow structure associated with food distribution and searching patterns. The burrowing patterns of the oriental mole cricket ( Gryllotalpa orientalis Brumeister, 1838) (Orthoptera: Gryllotalpidae) were investigated based on analyses of the relation between burrow morphology and plant distribution. To assess differences between horizontal burrows (HB) with and without vertical burrows (VB), the number of branching points, the length of the horizontal parts, the plant ratio of the burrow area, and the burrow fractal dimension were compared. The size of the burrow area was positively related to the degree of branching. Cyperaceae and Gramineae occurred less frequently, whereas Hydrocotyle sibthorpioide Lam. and areas with no plants were more frequent in the burrow area than in the quadrat area. Juncaceae and Persicaria thunbergii (Siebold and Zucc.) H. Gross ex Nakai occurred more frequently and Lindernia crustacea (L.) F. Muell. occurred less frequently in HB without VB than in HB with VB. The ratio of burrow length to the number of branching points was not significantly different between HB with or without VB. HB with VB had a nearly planar structure (higher burrow fractal dimension) than that of HB alone. HB structure and plant composition of the burrow area differed depending on the presence of VB.

Since the publication of Baker (2016) three additional burrow casts, unknown to the author, were located in the Natural History Museum, London (NHM) collection by George Beccaloni. These casts were provisionally identified as Gryllotalpa vineae. In order to establish whether this identification was correct a literature survey of the casts of mole crickets (Orthoptera: Gryllotalpidae) was conducted. Through this process a standardised terminology for mole cricket burrows has been established. The application of eccentricity measurements to burrow structures has identified measurements that can potentially be used to discriminate those species for which suitably detailed burrow descriptions have been made available. It is demonstrated that the eccentricity of the restrictions on either side of the bulb, as well as the eccentricity of the horn opening, are useful diagnostic characters.

We provide an updated checklist of Orthoptera and their allies for each Maritime province of Canada with details for 21 new species records. Drumming Katydid (Meconema thalassinum), recorded from Nova Scotia (NS) and Prince Edward Island (PEI), and Sprinkled Grasshopper (Chloealtis conspersa), recorded from New Brunswick (NB) are reported for the first time from the Maritimes as a whole. We report range extensions in the Maritime region for Australian Cockroach (Periplaneta australasiae; NB), Treetop Bush Katydid (Scudderia fasciata; NS), Short-legged Camel Cricket (Ceuthophilus brevipes; PEI), Spotted Camel Cricket (Ceuthophilus maculatus; PEI), Roesel’s Shield-backed Katydid (Roeseliana roesellii; NS), and Black-horned Tree Cricket (Oecanthus nigricornis; PEI). Short-winged Mole Cricket (Neoscapteriscus abbreviatus; NB) and European Mole Cricket (Gryllotalpa gryllotalpa; NS) are reported as adventives (non-native species that are believed to be not yet established), new to Canada from the Maritimes. Other new records for species not known to be established are Lined Earwig (Doru taeniatum; NS), Australian Cockroach (Periplaneta australasiae; PEI), American Cockroach (Periplaneta americana; NB), Brown Cockroach (Periplaneta brunnea; PEI), Smooth Cockroach (Nyctibora laevigata; NB), West Indian Leaf Cockroach (Blaberus discoidalis; NB), an unidentified Parcoblatta species (NB), Brown-banded Cockroach (Supella longipalpa; PEI), Praying Mantis (Mantis religiosa; NB), and American Bird Grasshopper (Schistocerca americana; NS).

Although this is a common insect in many parts of the United States, it is not generally found in great numbers in any locality, and, notwith standing its general distribution, the various staes of the insect seem not to have been describe or figured.While I am not yet able to clear up all the points in its history, I have studied the insect in all its stages, though I have not reared it from the egg to maturity, on account of the time required for it to develop—in all probability three years.

Burrow Morphology

In 1999 divers discovered a population of the burrowing mantis shrimp Rissoides (Meiosquilla) desmaresti (Crustacea: Stomatopoda) east of the St Tudwal's Islands, North Wales. This species has only sporadically been recorded in UK waters and commonly occurs in the Mediterranean. In summer 2000 the burrow morphology and distribution of these shrimps in the area east of the St Tudwal's Islands was investigated. Burrows were found at ten of the 15 sites investigated in a survey area measuring ∼18 km2. Burrow density varied from one to 11 burrows per 100 m2. The burrows were always recorded in sediments consisting of a mixture of mud, sand and gravel but were not present at sites with a high proportion of mud (>70%) or sandy sediments with very little mud ([les ]2%). Resin casts of six burrows revealed that these have a simple elongated U-shape, with an average length of ∼450 mm and depth of ∼160 mm. The average diameter of the burrow entrance was 19±2 mm and the diameter of the burrow along the horizontal section varied between 18 and 38 mm with a distinct constriction part way along.
