Hover Fly and Bee Fly Species Range

Hover Fly and Bee Fly Species Range

Bee Kinds Range

Off 2009 so you can 2018, 192 bee species (Hymenoptera: Apoidea: Anthophila) have been stuck from inside the Calanques Federal Park thru one another internet and you may pan trap stuff. It belonged in order to half dozen parents and you may 38 genera. Megachilidae are the absolute most varieties-rich members of the family, accompanied by Apidae and you will Halictidae, with 53, forty-two, and 43 types, respectively. Andrena Fabricius, 1775 is the brand new richest genus, with 33 species, whereas seven genera have been depicted by the only 1 kinds (Stelis Panzer, 1806; Protosmia Ducke, 1900; Pseudoanthidium Friese, 1898; Coelioxys Latreille, 1809; Chelostoma Latreille, 1809; Anthidiellum Cockerell, 1904; Amegilla Friese, 1897; Panurgus Panzer, 1806; Supp Table step 1 [online merely] ). By using the jackknife step one and you will dos spiders, the bee species fullness was projected as between ± nine.89 and ± . The fresh new observed richness thus represented 71.step three in order to 79.6% of one’s projected bee richness ( Desk dos). This new Chao1 method projected the latest seen richness as 76.8% of potential restrict fullness ( Table 2). Probably the most abundant kinds are Apis mellifera L. (276 individuals), followed by Rhodanthidium septemdentatum (Latreille, 1809), Rh. sticticum (Fabricius, 1787) (174 and you may 168 some body, respectively), and you can Lasioglossum transitorium (Shenck, 1868) (113 individuals). Fundamentally, 50 kinds (26%) have been represented by only one personal (singletons).

Ecological Faculties away from Bees

Regarding the environment characteristics away from nesting choice, i recognized 59 solitary bee kinds nesting more than ground, ninety-five solitary bee types nesting underground and 23 cleptoparasitic types, comparable to 30.eight, 47.9, and you may twelve.0% of the complete bee variety fullness, correspondingly. I perceived five personal varieties (bumble bees and you will honey bees-2.1%). In the end, the fresh new nesting choices out-of 14 species remain unknown (eight.3%- Supp Dining table 1 [on line only] ). About your flowery diet plan of bee kinds, we unearthed that 105 kinds (54.7%) foraged on numerous plant variety (we.age., generalist types, polylectic) and you may 51 kinds (26.5%) foraged using one bush family unit members otherwise one to/couple plant varieties (we.e., professional species, oligolectic). Into left thirty six bee types (18.8%), this new floral diet plan was not known (elizabeth.grams., to have cleptoparasitic kinds). Yet not, most generalist species exhibited a choice for 1 otherwise a few bush family ( Supp Desk step 1 [online merely] ). Towards forty-two singletons, 14 bee variety (28%) was in fact gurus, and 9 bee types (18%) was indeed cleptoparasitic ( Supp Dining table step 1 [online just] ).

A keen IUCN position is actually designed for 178 types (excluding the new varieties buildings and unfamiliar varieties). Some of those, 47 species was categorized since investigation deficient (DD-twenty six.4%), 124 variety was indeed the very least worried (LC-69.6%), half dozen types was indeed close threatened (NT-step 3.4%; Andrena ovatula (Kirby, 1802), Colletes albomaculatus (Lucas, 1849), Dasypoda argentata Panzer, 1809, Halictus quadricinctus (Fabricius, 1776), Lasioglossum prasinum (Smith, 1848), and you will L. pygmaeum (Schenck, 1853)), and one kinds try considered threatened (EN-0.6%; L. soror (Saunders, 1901)- Supp Dining table 1 [on the internet just] ). About three oligolectic varieties were one of many 7 threatened bee species. Good. ovatula and C. albomaculatus are professionals into Fabaceae, D. argentata are a specialist to your Caprifoliaceae.

From 2009 to help you 2018, 38 types of hover flies (Diptera: Syrphidae) was indeed trapped within the Calanques National Playground. They belonged to twenty four genera ( Supp Desk 2 [online merely] ). The most numerous genera have been Paragus Latreille, 1804 (33 people), Meliscaeva Frey, 1946 (fourteen individuals), and you may Sphaerophoria Lepeletier de- Saint-Fargeau Audinet-Serville when you look at the Latreille, 1828 (13 people), whereas 20 varieties (53%) was basically represented of the only 1 private ( Supp Table 2 [on the internet only] ). New bee flies (Diptera: Bombyliidae) was in fact illustrated from the 20 varieties, plus five singletons (25%) ( Supp Table 3 [on the web merely] ). The latest estimation off total species richness off hover flies and you may bee flies is actually ranging from 83 and you may 97 kinds utilising the jackknife step one and you will 2 indexes, correspondingly. Thus, the latest seen fullness depicted 59.8–69.9% of your estimated hover travel and you will bee fly fullness ( Dining table 2).
