Abstract
Chrysomelobia labidomerae Eickwort, ectoparasitic mite of chrysomelid 
beetles, is reported from 11 Wisconsin counties, from 16 of 82 adult Labidomera 
clivicollis (Kirby) beetles wild-caught in Wisconsin, and from 27 of 141 presum-
ably wild-caught L. clivicollis beetles from 13 Michigan counties. Wisconsin 
beetles harboring C. labidomerae were found in dry to wet-mesic, open habitats. 
A distribution map and comments are presented.
 
____________________
Mites in the family Podapolipidae are all haemolymph feeding parasites of 
insects, including Blattodea, Coleoptera, Hemiptera, Hymenoptera and Orthop-
tera (Kurosa and Husband 2013). These mites parasitize the subelytral space, 
trachea, reproductive tract and any surface area which may be penetrated by 
stylets with or without the aid of digestive enzymes for dissolving sclerotized 
tissue (Husband et al. 2008). Regenfuss (1968) first described the genus Chrys-
omelobia and species C. mahunkai based on one adult female on the beetle now 
known as Chrysolina graminis (Linnaeus) (Daccordi 1982) collected in Hungary. 
It has since been collected on a second chrysomelid beetle, Phytodecta sp., in 
Germany by the first author.
Chrysomelobia labidomerae Eickwort was discovered under the elytra of 
Labidomera clivicollis (Kirby) and described as only the second mite in this genus 
and the first from the Nearctic by Eickwort (1975), in which paper the mite's 
distribution data of Connecticut, Illinois, Indiana, Iowa, Michigan (Cheboygan 
Co.), New York, Ohio, Texas and Wisconsin (Rock Co.) were presented. This 
beetle is more widely distributed in eastern North America and is an obligate 
feeder on milkweeds, Asclepiadaceae (Clark et al. 2004, Riley et al. 2003). 
Chrysomelobia labidomerae was later found parasitizing four other species of 
chrysomelid beetles in the closely related genus Leptinotarsa in Mexico, includ-
ing L. decemlineata (Say) (Drummond et al. 1984), now a very widespread pest 
of potatoes (Clark et al. 2004). As yet, five species of chrysomelid beetles are 
reported to host C. labidomerae (Houck 1992). Abbot and Dill (2001) reported C. 
labidomerae from L. clivicollis beetles collected off Asclepias incarnata Linnaeus 
in southern Ontario, at Queens University Biological Station near Elgin, at a 
latitude similar to central Wisconsin and central Michigan. The first author has 
collected C. labidomerae from L. clivicollis beetles in southern Texas, at Lyford. 
The reported limits of this mite's distribution to the northwest are Cheboygan 
Co., Michigan, and Rock Co., Wisconsin, (Eickwort 1975) (see Fig. 1). 
Baker and Eickwort (1975) report that these mites do not parasitize eggs 
or larvae of L. clivicollis, that dispersal is accomplished only by adult females

transferring between adult beetles, and that the incidence of these mites on 56 
museum specimens of presumably wild-caught L. clivicollis from the vicinity 
of Ithaca, New York, was 14.3%. Abbot and Dill (2001) reported that, in mid-
summer, over 90% of 118 wild-caught males and females in southern Ontario 
had these mites.
Serendipitous collection of mites in the course of broader research on this 
beetle in Wisconsin by the second author provided us with new information 
about the range of habitats in which this mite occurs, the plants on which the 
beetles harboring mites were collected and new distribution data. These last 
were supplemented with new county data from museum specimens of Michigan 
beetles inspected by the first author.
Materials and Methods
Over the course of ongoing research into the milkweed specific fauna 
of Wisconsin, the second author collected many eggs, larvae and adults of L. 
clivicollis to voucher various aspects of the beetle's life history and distribution. 
Eggs and larvae were reared. When partly grown, these larvae were each iso-
lated and provided with sterile soil into which they burrowed to pupate. Adult 
beetles, either caught in the wild or reared in the lab, were quickly put into vials 
of 80% ethanol. These were later checked for mites by the first author. Some 
Figure 1. In the original description of Chrysomelobia labidomerae Eickwort (Podapo-
lipidae), a mite parasitizing Labidomera clivicollis Kirby (Chrysomelidae), Eickwort 
(1975) listed Cheboygan Co., Michigan, and Rock Co., Wisconsin, as rough northwest-
ern limits of the mite’s broad distribution across much of the eastern United States. 
These counties are cross-hatched. The shaded counties — Cheboygan, Dickenson, 
Ingham, Ionia, Kalamazoo, Lenawee, Livingston, Midland, Oakland, Oceana, Ottawa, 
Washtenaw and Wayne in Michigan, and Adams, Buffalo, Crawford, Grant, Kewaunee, 
LaCrosse, Manitowoc, Sheboygan, Vernon and Walworth in Wisconsin — represent 
new collection data. These data show counties in which these mites have been found, 
not their actual distribution.

specimens were retained by the first author, others were later deposited into 
the Insect Research Collection of the Entomology Department at University of 
Wisconsin — Madison. Prompted by this research into the distribution of the 
mite in Wisconsin, the first author studied pinned specimens of L. clivicollis 
housed in the University of Michigan Museum of Zoology to generate new dis-
tribution data for the mite in Michigan. Plant nomenclature follows Gleason 
and Cronquist (1991).

None of 86 adult Labidomera clivicollis reared in isolation in the lab in 
Wisconsin hosted C. labidomerae. Of 82 wild-caught beetles from Wisconsin, 
18 (22%) hosted these mites. Of 141 adult beetles collected in Michigan and 
presumably caught in the wild, specimens in the collection of the University of 
Michigan Museum of Zoology, 27 (19%) hosted these mites. 
Discussion
These data shift the known distribution of this mite in Wisconsin from 
Rock Co. (Beloit, 07 July 1962, R. Beardon) (Eickwort 1975), Beloit being central 
and right at the southern border, up through and all across the southern half 
of the state, a total of 11 counties (Fig. 1). These data shift the mite's known 
distribution in Michigan from Cheboygan Co. (21 June 1953, S. E. Neff) (Eick-
wort 1975), at the northern tip of the Lower Peninsula, to include at least part 
of the Upper Peninsula and to occur more generally around the southern half

of the Lower Peninsula, a total of 13 counties (Fig. 1). These data show where 
these mites have been found, not their actual distribution. Labidomera clivicol-
lis occurs throughout Wisconsin, though it is much harder to find in northern 
Wisconsin than in southern Wisconsin. 
These data include the first association of the mite with L. clivicollis col-
lected from a spectrum of open habitats, from dry sandy prairie through dry 
south-facing roadside bank, open roadside, moist roadside to wet-mesic prairie, 
as well as beetles on four local food plants that are associated with this spectrum 
of habitats, typically growing in situations ranging from dry to moist: Asclepias 
viridiflora, A. verticillata, A. syriaca and A. incarnata.
That no mites were found on the 86 lab-reared adult beetles is not a 
surprising result. Baker and Eickwort (1975) stated that mites parasitize only 
adult beetles to which adult females disperse from other adult beetles. These 
86 lab-reared adults never had contact with any other beetles from which mites 
might have been acquired. Our frequencies of occurrence of 22% on beetles 
wild-caught in Wisconsin and 19% on presumably wild-caught Michigan beetles 
are similar to the 14.3% reported on presumably wild-caught New York beetles 
(Baker and Eickwort 1975). In contrast, Abbot and Dill (2001) reported that, 
in midsummer, over 90% of 118 wild-caught males and females in southern 
Ontario had these mites.

Of 82 wild-caught beetles from Wisconsin, 18 (22%) hosted these mites. Of 141 adult beetles collected in Michigan and presumably caught in the wild, specimens in the collection of the University of Michigan Museum of Zoology, 27 (19%) hosted these mites. DiscussionThese data shift the known distribution of this mite in Wisconsin from Rock Co. (Beloit, 07 July 1962, R. Beardon) (Eickwort 1975), Beloit being central and right at the southern border, up through and all across the southern half of the state, a total of 11 counties (Fig. 1). These data shift the mite's known distribution in Michigan from Cheboygan Co. (21 June 1953, S. E. Neff) (Eick-wort 1975), at the northern tip of the Lower Peninsula, to include at least part of the Upper Peninsula and to occur more generally around the southern half 3Husband and Williams: Notes on Chrysomelobia Labidomerae (Acari: Heterostigmata:Published by ValpoScholar, 20142014 THE GREAT LAKES ENTOMOLOGIST 49of the Lower Peninsula, a total of 13 counties (Fig. 1). These data show where these mites have been found, not their actual distribution. Labidomera clivicol-lis occurs throughout Wisconsin, though it is much harder to find in northern Wisconsin than in southern Wisconsin. These data include the first association of the mite with L. clivicollis col-lected from a spectrum of open habitats, from dry sandy prairie through dry south-facing roadside bank, open roadside, moist roadside to wet-mesic prairie, as well as beetles on four local food plants that are associated with this spectrum of habitats, typically growing in situations ranging from dry to moist: Asclepias viridiflora, A. verticillata, A. syriaca and A. incarnata.That no mites were found on the 86 lab-reared adult beetles is not a surprising result. Baker and Eickwort (1975) stated that mites parasitize only adult beetles to which adult females disperse from other adult beetles. These 86 lab-reared adults never had contact with any other beetles from which mites might have been acquired. Our frequencies of occurrence of 22% on beetles wild-caught in Wisconsin and 19% on presumably wild-caught Michigan beetles are similar to the 14.3% reported on presumably wild-caught New York beetles (Baker and Eickwort 1975). In contrast, Abbot and Dill (2001) reported that, in midsummer, over 90% of 118 wild-caught males and females in southern Ontario had these mites.AcknowledgmentsHusband thanks B. O'Connor and M.
