Locust digitate leafminer moth

Locust digitate leafminer moth

Parectopa robiniella

A species of Parectopa

The locust digitate leafminer (Parectopa robiniella) is a moth of the family Gracillariidae. It is native to North America, but was accidentally introduced to Italy, where it was first found in 1970. It has now been recorded from Italy, France, Germany, Slovenia, Croatia, Austria, Slovakia, Romania, Ukraine and Hungary. The wingspan is about 5 mm. The moth flies in two to three generations per year in Hungary. The larvae feed on Robinia species, including Robinia pseudoacacia. It mines the leaves of the host plant. The common name is derived from "digitate", referring to the "finger-like" excavations all around the margins of the central blotch of the mine.

Life Cycle of Locust digitate leafminer moth
Egg The egg stage is the beginning of the locust digitate leafminer moth life cycle. Eggs are often laid on host plants and are small and inconspicuous. Over time, the embryos develop inside, preparing for the larval stage.
Larva Upon hatching, the larva (also known as a caterpillar in locust digitate leafminer moth) feeds voraciously, growing rapidly. This stage is characterized by multiple molts, each allowing the caterpillar to increase in size. It is primarily focused on feeding and growth.
Pupal The fully-grown larva forms a pupa. During this stage, the locust digitate leafminer moth undergoes remarkable transformation. Inside the pupa, it reorganizes into an adult, with many undergoing color and shape changes largely hidden from view.
Adult Emerging from the pupa, the adult locust digitate leafminer moth's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Locust digitate leafminer moth
Since locust digitate leafminer moth is a type of moth at its adult stage, one could use light traps at night or bait traps with sugary substances to attract adults. In its larval stages, pheromone traps are less effective as caterpillars are not typically attracted by them.
Rectangle
What is the Best Weather to Observe Locust digitate leafminer moth
Warm, dry, and calm nights are ideal for attracting adult locust digitate leafminer moth to light traps. Larval and pupal stages may be easier to find during mild weather when they are actively feeding and not in diapause.
Rectangle
How and Where Can You Find Locust digitate leafminer moth at Different Life Stages
Egg Locust digitate leafminer moth eggs are typically laid on the underside of leaves of the host plant. To find them, inspect the host species carefully, using a magnifying glass if necessary.
Larva Locust digitate leafminer moth larvae are leaf miners and create visible trails on leaves. Look for these distinctive trails on host plants to locate larvae.
Pupal Locust digitate leafminer moth pupae may be inside leaves or in the soil near the host plant. Gently unroll mined leaves or sift through the top layer of soil to find pupae.
Adult Locust digitate leafminer moth adults are small moths and can be trapped by setting up a light trap after dusk or by using a baited trap with a sweet, fermenting mixture to attract them.

Brown birch slender
Brown birch slender

Parornix betulae is a moth of the family Gracillariidae. It is known from all of Europe (except the Iberian Peninsula, the Balkan Peninsula and the Mediterranean islands), east to Korea. It was recently reported from Canada, with records from Québec, Ontario and British Columbia. The wingspan is 9–10 mm. The head is fuscous, more or less mixed with white. Palpi white, sometimes with dark fuscous subapical ring. Forewings are grey, irrorated with dark fuscous and white ; numerous costal strigulae, a spot in middle of disc and another posteriorly,and two dorsal spots white ; a blackish apical spot ; cilia with two dark fuscous lines, tips round apex white, beneath apex with a third dark fuscous line. Hindwings are grey.The larva is whitish green ; dorsal line dark green ; head brownish ; segment 2 with four black spots. Adults are on wing in May and August. The larvae feed on Betula alleghaniensis, Betula grossa, Betula humilis, Betula obscura, Betula papyrifera, Betula pendula, Betula pubescens, Betula nana and Betula utilis. They mine the leaves of their host plant. The mine starts as an inconspicuous lower surface corridor, mainly recognisable by its brown line of frass. In the next larval stage a lower-surface blotch is made, that soon develops into a tentiform mine. The frass is deposited in a clump in a corner of the mine. After leaving the mine the larva continues feeding in a downwards folded leaf margin, that is fixed with silk.
